This studio is exactly what Emmanuel says it is. We didn't get to Meet him but his friend Dior came to let us in, showing us where everything is and how to work it and apologising for being (about one minute) late!
The studio is a good size for Paris and nicely furnished with a super comfy bed. We only stayed two nights so we weren't using the cooking facilities but there are enough there to make a good meal. Or if you're not a cook there's a microwave.
The building is a lovely old building with lots of charm - the stairs are particular for this age of building and are shallow, different depths and slightly uneven which, whilst perfectly safe, is an odd sensation if you've never experienced it before.
