I stayed one night at Andrei's apartment, and given the opportunity I would stay there again. Andrei was friendly, flexible and quick to answer my questions. Although I didn't meet him in person, as I arrived during off-hours, he arranged for his friend Florian to let me in and drop my bags off early. The apartment was a very short walk to the tram, and was in the middle of a lively neighborhood filled with shops and restaurants (lively during the day, but quiet at night, which I appreciated). Thanks for a great stay, Andrei!
