Very well located : close to the Grande Place and the Central Station. Quiet at the same time, clean.
There is one double bed and one of of my friends was on the sofa.
So just one piece of advice if somebody has to stay on the sofa : take earplugs (the clock is noisy) and take a night mask because there is no shutter or custain in the living room.
But do not hesitate to take that flat. It is a very nice place !
