Our stay at the apartment was very pleasant. the hosts were very kind and helpful. Initially we had booked another apartment of Sascha and Marina, which we found was not what we wanted because it was ground floor. As soon as we mentioned it they immediately sent us alternatives and we chose this one (it was as beautiful as the first). The room was very clean, in a very good location and next to the metro station. You need max 15 minutes to arrive at the center. To questions we asked Sasha and Marina about our apartment, they answered immediately. The only negative was the internet that didn’t work so well. There was problem with the connection but it was ok for us because we had 4G. In general very nice and familiar apartment! I would visit it again if I came to Vienna again.
