The apartment is located in a quiet courtyard. We with children were comfortable climbing narrow stairs (it was difficult only with bulky luggage). Nice apartment for rent.
I liked the location. Convenient walking access to tourist places, if it's a necessary due to weather conditions - there is a taxi station nearby. We don't use public transport, so I cannot say anything. A variety of cafes (take away too) and shops are within walking distance (5-10min). You can see the residential quarter to see and try to feel Vienna.
On arrival, the owners introduce the apartment and its functional equipment, and help with advice. The arrival left a bright pleasant impression.
