Josef's appartment is small but perfectly arranged. Very clean and in a convenient location (in a walking distance from public transportation (easy to reach from/to the airport) but also to downtown, various supermarket really close to it). It seems like it was recently renovated (was in perfect condition). There was a bit of noise from the kids on the near appartment but in overall that was pretty quiet . Josef has been very responsive and helpfull to our messages and welcomed us with his wife on our arrival. Definitely a very good place to visit Vienna, higly recommend it.
