The place is clean, linens are soft and bed comfortable. The location is very central and it's convenient to get places from there. The fact that it is attached to a hotel gives a level of comfort and ease of check in and check out. We had an issue with the fan in the room and the hotel staff quickly helped us replace it.
Now the not so good. The place is. Wet close to a busy street and you can hear traffic day and night. There is no AC, which we knew but thought we'd manage as it seems quite common in Vienna. But we were there during the massive heat wave and it turned out to be a major issue. The street is narrow and there is no air movement at all day or night. Very very hot! Another thing to keep in mind, it really is like a hotel room. Bed and bath. No kitchen at all. I would chose an actual hotel over this place if that's what we were looking for. To sum it up, great location, clean room and good service. Lacking a kitchen and an AC. Noisy street.
