The apartment was really amazing. Very good location (1 min walking from the public transportation, 1 min walking from a supermarket), three big rooms and very nice kitchen and living room. The heating system was perfect (winter is quite cold in Vienna). Dominik is a great host, always there when you need him. Check-in and check-out have been really easy. I enjoyed a lot staying there and visiting Vienna.
On top of all these things I have to say that the ratio price/quality is one of the best ones I found here in Airbnb.
Thanks again Dominik, if I come back to Vienna I will stay in your apartment for sure.
