I came to Vienna with my partner for a scientific conference. We needed a (centrally located) place to work a bit before the conference, to decompress after 8 hours of a conference, and a good base of operations for going out into Vienna. This place was just that! Andrei, the host, was very great about our check-in and check-out times, and extremely responsive to messages. He also gave us a lot of great places to check out nearby. I would definitely stay here again!
