Nice little place to stay while in Paris. The building is very nice and has been renovated to a good standard. The studio itself is small and accessing the mezzanine is a little wriggly - I wouldn’t recommend it to very tall people, but as it were, it was ok for us.
Unfortunately, upon arrival, the studio wasn’t ready for us and we had to wait for quite a long time. The staff was clearly busy trying to fix the situation (it wasn’t just our studio) and they were nice enough, but in the end, it was a little inconvenient to have to wait. Overall, I’d still return (though maybe not to one of the studios under the roof), as the location was really very good.
