We stayed for three nights during New Years holidays. Flat was very comfortable for two people. Comfortable sleeping room and bed. There are supermarkets in the nearbies, so it was easy to have breakfast and dinner in the apartment .The shower is not so big, but is ok.
Very near to the center, all the louvre-notre dame are reachable by walk.
Wifi available and very fast!
Next time we we will be in Paris we will come there!
