This is a perfect place to stay in Vienna, especially if you travel by car.
Location is nice - good starting point for Schonbrunn sightseeing, not too far from the Metro. Closest local super-mart is just 5min walk.
Room itself is very spacious (you have 5 separated spaces - bedroom, kitchen, hall, bathroom and toilet), everything decorated with taste (quartz panels in the bathroom are really pleasant to look at, also there is a wooden parquet on the floor). Bedroom has the direct entrance to the garden.
The building itself it 150 years old what may be a treat for people interested in old architecture.
However you need to be aware that after last redecoration cracks in the wall appeared in several places (it is already addressed to the architect but not sure when they will be fixed - so don't be surprised, but don't let it bother you too much).
Also the place is located next to 4 lane street so you can hear cars droning in the background - not very irritating but worth mentioning.
The other key feature is the internal parking lot - especially crucial if you don't want to keep your car on the street.
We are definitely going to visit again! :)
