My stay at Michael's place was very pleasant. The room was well set-up for a solo traveller and having the shower in the room was a plus for me. Michael's communication was excellent and very clear, meaning that I did not have any questions at all. The location is great, set in a quiet neighbourhood that is quite close to the central 1st District (about 20 minutes walk). Would highly recommend this place for anybody looking to spend a few days in Vienna.
