Very great location: safe, beautiful, great surrounding shops and restaurants. The building itself is very safe and access secured. The studio itself was clean and comfortable. Keep in mind it is much smaller than the pictures make it seem, though, and the windows are very small with no good views.
The studio has everything you might need for a lengthy stay in Paris with a bathroom, cable tv, and kitchen.
Please be warned that this studio is on a floor that is only accessible via a very small elevator. There is no stair access. We unfortunately had an incident where we came back to the studio late at night and the elevator was broken. Julia was unreachable, and we did not have anyone else to contact except calling the emergency elevator number. Someone from that company was able to come out and with some persuasion, he unlocked the elevator door so we could figure out how to reset the elevator. Being locked out of your accommodation in a foreign country was quite frightening. With the elevator being our only mode of getting to the studio, it was quite frustrating.
Overall, Julia is a very nice host that truly cares about making you comfortable. She apologized for our lock out incident and made sure we were comfortable for the rest of our stay. I would recommend this studio to anyone as long as small elevators don't scare you.
