The location is good, easy to reach and we slept well. But we didn't like to spend much time in the apartment due to the high humidity (not surprising in a cellar). All the textiles (sheets, after a while our own clothes) were unpleasantly moist. There is no option for fresh air as the window opens to a wall in which there is a noisy radiator system. The air-conditioning, which you have to keep on due to the moisture, is also quite loud and there is also unfortunately a very noisy high-heels upstairs neighbour who constantly walks up and down from 7am to 1am. (Some people are not disturbed by that I know :).
Maybe it is better during the warmer months! But as I said, we slept well!
