Carlton Opera Hotel Vienna is a charming family-run hotel housed in an elegant Art Nouveau building in the heart of Vienna's bohemian Freihausviertel quarter — a lively neighbourhood of galleries, restaurants and bars in the 4th district (Wieden). The hotel occupies a quiet one-way side street just a short walk from the famous Naschmarkt outdoor market, and is perfectly placed for exploring Vienna on foot: the State Opera House and the Musikverein are 10–12 minutes away, while the Kunsthistorisches Museum, the Naschmarkt and Karlsplatz are just minutes from the door.

The hotel's 65 individually designed rooms feature high ceilings, parquet floors and Art Nouveau character, and are all equipped with air conditioning, flat-screen satellite TV, minibar, safe and private bathroom with hairdryer. Tea and coffee making facilities are provided in every room. Studios and fully equipped apartments with kitchenettes are also available — ideal for longer stays. A generous daily buffet breakfast is included. Free Wi-Fi is available throughout the building.

Guests can relax in the hotel's sauna and fitness room, both free to use. An airport shuttle service is available on request (surcharge), and public parking can be found nearby. The Paulanergasse and Resselgasse metro stations are just a few minutes on foot, connecting guests to all parts of the city.
