My wife and I stayed at the Singerstrasse 21-25 Aparthotel for one night (Classic Apartment) in November 2025. We enjoyed our stay. We arrived very early in Vienna and dropped our luggage at the hotel. The staff then very kindly worked really hard to get the room ready and we managed to check in two hours early. On check-out, there was no possibility of staying later, so we again left our luggage and walked around the lovely Christmas market. The room was lovely, large, modern and had everything we needed. The shower was especially wonderful. One small point; the TV is not smart and has only local channels (we found one in English) and all the inputs are disabled, so we watched our shows on a laptop. Not a big issue as Vienna is beautiful and you should be out enjoying it. The hotel is in a perfect location; a short walk to the center but far enough away to be quiet. As mentioned, all the hotel personnel were very friendly and helpful. Strongly recommend!
