Isabel's apartment is very nice, new, cozy and quite big for a flat in the City center. Most importantly: it is quiet. You can either walk to the city center (around 30-40 min), or take the bus or the historical tram (must do!).
Isabel provided us quite spontaneously with another blanket. The communication was good. The only problem we had was to open the frontdoor, it took us each time several minutes because the door is really hard to open with the keys. But besides that, I would definetly recommand this apartment
