A great little little apartment if you're looking for a place to stay in Paris without blowing your budget. The bed is a hideaway couch but it was the most comfortable hideaway that I have ever slept on. It could get a little noisy at night sometimes from a nearby bar but otherwise it was very peaceful.
The only warning I would offer is that I am 6'6" tall (~2m) and the shower was a very tight squeeze to get in and out off. Otherwise the apartment was great!
