The room, the location, cleanliness and everything else was superb. The hotel is quiet, newly redecorated, modern and very tidy. I would definitely recommend this place. One little improvement that I would suggest is breakfast. While the breakfast is provided every day, their options are very limited (fresh bread, butter, jams, coffee and tea). As not everyone eats jam, there should be at least some cold meats and small selection of fruits to make this breakfast a little bit more appealing. Otherwise, Room 55 is a gorgeous place to stay when in Vienna.
