The flat is very well located in a main street (but you won't hear any noise !).
Everything was clean.
Shower could be improved (plastic curtains with a bit of mold)
Be ware that the flat is located at the top of the building and you will need to take the stairs twice to get to the apartment. At the time, the lift was not working all the way up so I had to use the lift to the 4th floor, walk up to the 5th floor and then continue to go up through an unconventional alley with a second stairs that lead you up to the last floor which looks more like "the atic of the building". It is a bit strange but you get used to it. Just bear in mind it will take you like 5 minutes to get to the apartment once you enter the building.
All logistics worked fine.
Very good location around art galleries and nice restaurants, easy to walk to the center and everywhere.
I would recommend for a couple or one or three nights stay. Look or something else if you are not in a budget and looking for something more romantic.
