We stayed for two nights in Sam's studio. The location is excellent. Just minutes from the canal St-Martin and plenty of bars and restaurants, but the courtyard is enclosed enough that you don't hear a sound from inside the studio. Check-in was smooth and communication was speedy throughout our stay. Of course, the place is small (this is central Paris, after all!) but it has everything you could need for a short stay and serves as an excellent base for exploring the city. Would recommend.
