I had a peaceful 3-week stay in Borzou's cozy studio. Compared to other studio apartments I've stayed in in Paris, this one has enough space and is set up to function really well. As well, the pull-out bed is comfortable. It's a quiet building, and a quiet area of the city except on weekends. The location is fantastic for exploring both right and left banks on foot; metro lines are close.
The only problem I had was that I lost my cell phone connection while in the apartment, as did my friends who came to visit. But there's also a phone line, and wifi in the apartment :)
I thoroughly enjoyed my stay and can recommend staying at Borzou's studio!
