My family and I really enjoyed our stay. Martin was exceptionally helpful and staying at his place made our visit to Vienna even more memorable. The apartment is very spacious, and each of the four of us had plenty of room. Since there is no elevator, it is a bit of a walk all the way to the fourth floor, but it is definitely worth it - the stairwell is pretty itself, and the views out of the apartment windows onto the tile roofs and tree tops in the courtyard are gorgeous. Martin even had an apartment guide printed out - which answered all our questions about the apartment, and even more (such as directions to the main attractions and sightseeing recommendations). Location is very convenient - we were a short Uber ride away from the main sights. Overall, great value for the price. Definitely recommend!
