Martin was a really great host, he greeted us when we arrived and helped us out immediately when we needed some tips. Otherwise, he made sure we had everything we needed at our disposal and we barely noted his presence. It was almost as if we had the whole place for ourselves.
The location is about 20 minutes from center by tram or bus, until late at night.
All in all, we had a great stay and I recommend choosing Martin's place even for several nights spent in this fascinating city!
