Nice clean flat located at historical building of 1913 y. Apartments are smaller then they seem at the pictures, but for us (2) was OK. In fact you have 4 sleeping places (double bed and double coach). Important was flexible check–in / check–out: we arrived early in the morning and Nikolay was very polite (thanks to Him!) to wait for us (because of our flight delay). Have everything you might need: towels, slippers, iron, hairdryer, washing machine, bed linen, etc., even dvd films to watch. Convenient location to the center (direct U–ban to the center walking street of Vienna ~ 20 min (including walking to the U–ban or tram and the road it self)) . Spar shop in 2–5 min walk from the center.
