I would give this place 3.5/5, but unfortunately unable to give half stars.
Pros: Location is amazing! Walking distance to Louvre, restaurants, etc. Much cheaper than hotels in the area. Lots of Japanese food in the area which was a nice fall back for us during our trip.
Cons: Very small space. Good for one person, but quite tight for two people. It was also a bit dirty. Pillows were flat and stale, towel had brown marks, and the washer had a lot of grime inside. I needed to wipe it down several times with Clorox. The person who checked us in was also a bit rude - we wanted to check in a little after 3 pm, but he was pushy for 1 pm.
