This is a great place to stay. Pretty easy to get to any other part of Paris via Gare de Lyon station which is a short couple minutes walk.
Vincent from the agency was lovely enough to allow us to check in early which was great. It allowed us to drop off our bags and go exploring.
Some things I will point out, which didn't dampen our enjoyment of the place one bit is that there appeared to be a hospital near by which meant that there were a lot of sirens and I mean a lot. Some people may find that distracting.
Also the lift is very small so if you have a lot of luggage or big luggage you have been warned. I thought the lift was charming.
If I was to come back to Paris I would definitely stay there again.
