I stayed in the flat for four days with my girlfriend. We had a really great stay. The flat is small and in an old building, but really cosy and has everything you need. Even though the street can be quite loud, with windows closed you can barely hear anything, so it was no porblem getting a good night's rest after exploring the city. The location is perfect, it is possible to walk to a lot of sights and there are also lots of supermarkets, bars, restaurants, bakerys and a metro station in less than 5 minute walking distance. The communication with Stefan was also perfect, as he always answered really fast, provided us with a lot of information about the area and even messaged us during our stay to tell us about a festival that was happening in the city that day. So I can really recommend staying there, if you are looking for an affordable accomodation close to the city centre.
