What STD, SUP and DLX mean: decoding hotel room categories

You open a hotel listing and instead of a normal description there's nothing but abbreviations. STD, SUP, DLX, Junior Suite, Executive. It's not easy to figure out right away what exactly you're paying for.

There is no single global room classification system. Categories are set by the hotel itself or the booking platform, and they do it differently (as of 09/2026, category overview from Leonardo Hotels). A Deluxe room at one hotel often means exactly the same thing as a Superior at the one next door.

Below we'll decode the main categories and codes. You'll understand how Standard differs from Superior, when Deluxe is worth the extra cost, and why a junior suite and a full suite are structured differently.

How hotel stars differ from room category

Many people confuse hotel class and room category. Stars describe the building as a whole, while the specific room is what you choose inside it.

Hotel quality in Europe is assessed by Hotelstars Union. The system is voluntary and awards from one to five stars for services, facilities, and service quality (as of 09/2026, Hotelstars Union). Room category is not tied to these stars.

Verified on 14.09.2026 on the official Hotelstars Union website: the star rating evaluates the property, not the individual room. That's why a five-star hotel can have both basic Standard rooms and expensive Suites at the same time.

The practical takeaway for you is simple. Look at the room category first, and only then at the stars. Stars tell you about the hotel's service, while the category tells you about your room.

💡 In short:

• A five-star hotel can have both basic Standard rooms and expensive Suites at the same time.
• Hotel stars and room category are not directly connected.

Basic categories: Standard, superior, and deluxe

Standard opens the category list at any hotel. It has everything you need for an overnight stay: a bed, a private bathroom, climate control. Most rooms in a hotel are usually at this level.

Superior is one step up. Most often it's the same room with more square footage or a better location: a high floor, a quiet wing, a better view (as of 09/2026, Leonardo Hotels data). The surcharge for Superior is usually small.

Deluxe occupies the third level at most hotels. Here you get better finishes, more expensive appliances, a wider choice of views: city, river, sea. There's still no separate bedroom, the whole room remains one space.

Bed type and room category are generally not connected on most platforms.

Connecting and family rooms: Connected and Family

Connected Rooms join two rooms with a connecting door. Each room has its own private space, and you can move to the neighboring room without going into the hallway. The category inside can be anything: Standard, Superior, or Deluxe.

This setup works well for large families and groups of friends. You should look for Connected if you're traveling with kids or a big group. The catch is that connecting rooms are not available at all hotels.

Family is designed for families with children. The room includes several spaces: a bedroom and a living room. Sometimes you'll also find one-room Family options. Furnishings are usually at the Standard or Superior level.

On booking platforms, the Family category is usually not offered for solo travel, it's assigned for family occupancy.

Suites: From junior suite to presidential suite

The name Junior Suite hides an enlarged room with a sitting area. The sofa and coffee table are in the same space, with no dividing wall. That's why a Junior Suite is considered a junior suite rather than a full suite.

Mini Suite repeats Junior Suite, but with less square footage and more modest finishes.

A full Suite is structured differently. Here the living room is separated from the bedroom by a wall or door. The room often consists of several spaces: a bedroom, a living room, sometimes an office.

Presidential Suite sits at the very top. It occupies several rooms on the top floor: bedrooms, an office, bathrooms, a dining room, and balconies. The size of these rooms can reach up to 200 m² (as of 09/2026, Leonardo Hotels). Hotels usually have one to three of them.

Ambassador and Royal Suite are one step below Presidential. The finishes and amenities here are more modest, and these rooms are also few in number at any hotel.

Standalone accommodations: Bungalow, villa, and apartment

The Bungalow category includes standalone one- or two-story houses on the hotel grounds. Guests have access to all the infrastructure, and the interior level ranges from Standard to Deluxe. Bungalows are often located by the coast or directly over the water.

A Villa is larger than a bungalow and includes a separate house with several rooms, a terrace, and balconies, sometimes with a jacuzzi. A villa is rented as a whole, and you pay for the entire house. Meals are usually not included, but a kitchen is typically available.

The name Apartment hides a room with a kitchen and dining area. You can live here independently, which is why apartments are chosen by couples, large families, and groups of friends. Apartments are usually listed as a separate accommodation type, lodging with a private bathroom and kitchen.

Studio is close to an apartment and consists of one room with a kitchen area. This option works for you if you want to cook for yourself and avoid overpaying. Studio differs from a regular room precisely by having a kitchen or kitchen area.

What the abbreviations STD, SUP, and DLX mean

Codes like STD, SUP, and DLX were created by hotels for their internal systems. There is no single standard behind them, each hotel defines the abbreviation itself. STD means Standard, SUP means Superior, DLX means Deluxe.

Booking platforms may label categories in their own way. Always check the designation in the description on the platform itself.

What this means for you in practice. Always open the room description and check the size, bed type, and view. The category name alone guarantees almost nothing.

⁉️🤔 Frequently asked questions

What does SUP mean in hotel booking?

SUP stands for Superior. This marks a room one step above Standard with more space or a better view.

How is Junior Suite different from Suite?

Junior Suite remains one room with a sitting area. In a Suite, the living room is separated from the bedroom by a door or wall. If you need a quiet corner for work or separate sleep for a child, book a Suite, not a Junior.

Which is more expensive, Superior or Deluxe?

Deluxe almost always costs more than Superior. The surcharge depends on the specific hotel, so compare the two rooms for the same date.

What do the codes DBL and SGL mean in booking?

DBL stands for Double, meaning a room with one large bed. SGL means Single, a single room. Both codes describe bed type and occupancy, not room class. Always check the exact designation in the description on the booking platform itself.

Is it worth paying extra for Deluxe?

Paying extra for Deluxe is justified if the room becomes part of your vacation. A panoramic view, new finishes, and a quiet wing are noticeable every evening. For a short trip with early departures, the extra square footage is rarely worth it.

In short: what to book

Room category matters more than hotel stars. First decide how much time you'll spend in the room, and only then choose the level.

Selection matrix:

• If you're on a short trip: book Standard or Superior.
• If you're traveling as a couple for a few days: look at Deluxe or Junior Suite.
• If you're with kids or staying for a long time: book Suite or Family.
• If you need a kitchen: look at Apartment or Studio.
• If you want a separate house with a terrace: look at Bungalow or Villa.
