Vincent is a very nice guy and always ready to help! The room is in a very central location, everything is very close and you don't need to use the tram or other public transports. The flat is nice and bright, and we had big windows in our room...though sleeping till midday could be difficult ;)
However, it could be little cleaner and a dustbin in every room would be usefull, too. The mattresses were very soft - too soft for some people. A couple more hooks around the flat and especially in the bathroom, would be usefull, too.
