The location is really good. Close to all things Pigalle, but the studio is really quiet. There are a couple of vegan places close by that I enjoyed going to (including Mesa which is like 3 minutes away, and Cloud Cakes).
The check-in was easy and they were kind enough to do an earlier check-in.
Have in mind that the studio is very small, so I'm not sure if a couple would have a great time there. For a solo traveler works fine.
