We recently stayed for 4 nights in Dina's apartment. The apartment was great lovely and spacious. The terrace is amazing so relaxing sitting outside. We travelled with 2 children and it was perfect for them. I don't think it would be suitable for very small children due to the large number of stairs to climb as there is no lift. The location is perfect, a couple of mins walk to the underground and 4 mins to Stephansplatz from there. We tried a wonderful restaurant called Meixners in the local area - highly recommend.
