Andy was very friendly and helpful with us, welcomed us very well and solved all our doubts with ease. The flat is fully renewed and with many stylish details that make it really comfortable. All the rooms are very spacious. It is as nice as it looks in the pictures!
The location is perfect for sightseeing or shopping, in my opinion it is situated in one of the best neighbourhoods in Vienna. Very well connected to the rest of the districts with the U2, from there it is very easy to get to all of Vienna's landmarks. You can even travel further afield with the S-Bahn from Praterstern station, which is only a few blocks away.
I would definitely rent the flat again, it is ideal for a trip with friends, family and even long stays.
