We had a lovely stay. The apartment is well situated - easy access to Gare du Nord by metro and easy to access many areas of Paris by foot and metro.
It is beautifully appointed and both beds are comfortable. Kitchen area is well equipped and very good shower.
It is very small, and as it is ground floor in a small courtyard it is rather dark, and it only has one window in the front door and another in the bedroom. We had lovely weather during our stay and were out all day so it suited us perfectly. It would be hard to imagine spending all day there on a wet day.
Lovely hosts and good communication.
