No control over room heat and you are required to turn in and retrieve key from front desk each and every time you come and go.
Great location on Mariahilferstrasse -- central, safe, close to transportation, food, shopping, historical sites, etc. Hotel is spread out on various floors throughout the building. Room 222 was clean, quiet, good hot water and shower, comfortable bed, excellent wifi connection, balcony (not much of a view, but fresh air and sunshine nonetheless!) -- probably one of the best rooms in the hotel! The best attribute, however, is the family operating the hotel -- friendly, helpful, pleased to be of service, mostly English-speakers -- they seem to truly appreciate their guests and couldn't be more properly suited for being hoteliers, a real pleasure!
