That apartment has a wonderful location, close to the public transport station and in 5 min from the Moulin rouge. Near the house there are several cafes and shops.
Vincent allowed us to leave our stuff earlier than check in time. Also in the check out day we were allowed to keep our stuff till evening.
There were some problems with cleaning, but location of the flat and communication with host allow me to give 4/5 mark.
If you are looking for the flat in the center just to sleep at night- this is a perfect option.
