Even though the host was not available personally, we were given precise information to allow us to check ourselves in without too many problems.
The flat is spacious, a 15 min walk from district 1 which is the center of town.
The closest underground stations Taborstraße and Schottenring are approx. 600m, which is a fairly easy walk if you are not carrying any heavy luggage.
The flat is mostly clean apart from a few patches. The beds are nice and comfortable.
All in all a pleasant stay. Fair for the price.
