This is a great studio apartment, it's in a really quiet location, once you've gone into the courtyard and it felt very private.
The room itself is immaculate, the bed really comfortable. It's a perfect crash pad for seeing Paris. We ended up walking everywhere but it was close to the Metro, and about 15 minutes walk away from Gare du Nord. We flew to Paris but if I did it again I'd definitely go by Eurostar, as I'd forgotten that the airport is a good 45 mins away by train.
Chris couldn't do enough to help us, he recommended a great restaurant for the first night (Bonhommie) and allowed us to leave our bags as we had a later flight. He was super quick in responding if I had a question, and Paris was just magical.
