I stayed here with my wife and it was perfect for just us two. The upstairs is just the bed and the bed only, just an FYI. The downstairs has a couch, kitchenette, TB, and washer. There's a drying rack provided to dry your clothes.
The location is a 5 minute walk to the Louvre. Central to everything, and it's in a really nice area.
I will warn you about the stairs! There's no elevators, and it's on the 6th floor. Don't forget anything when you leave, unless you want to sweat.
Tips: turn on the heaters. Use hot water sparingly when showering. Only about 10-15 minutes with of hot water at a time.
I would recommend for couples.
