The location of this studio is perfect - it's a very central location, we had a blast exploring the surroundings, and it was very easy to catch the subway and get virtually anywhere in Paris.
The studio is small, definitely for a single person, a couple, or 2 very good friends. It doesn't offer much storage space, and you won't cook a feast in the kitchen. The size of the place didn't really bother my boyfriend and I though, we were roaming around Paris and only using the studio to crash at night and shower. But if that's not your style of travel you've been warned!
