Robert is an excellent host and he is there for everything you'll need. He replies fast to the messages , he is also very helpful since he recommends beautiful places to visit in Vienna. The house is close to the center of the city and the tram station is a 2 minute walk from home. The apartment is perfect, very clean and nicely decorated. We really enjoyed our stay there and If we travel again to Vienna we will definitely choose this apartment again. Totally recommended!
