Great place to stay a weekend. Despite not having the full place to ourselves, it certainly felt like we had all the privacy we could have asked for. With the full bed and a pullout, you could sleep three people comfortably though the space on the floor for bags would be limited.
Easy check-in and in-and-out access that would have worked perfectly fine even if Simo wasn't there.
Everything in Paris is walkable and there are plenty of bars within a mile or so in the evening. Although a bit farther from the center of Paris, subway access makes it trivial if you don't feel like hiking across town.
Overall similar price to a hostel for two of us but much, much more comfortable!
