Ruth is a very nice and friendly host. She told us some things about the neighbourhood. It we had a question, she responded very fast via mail.
The apartment is small but cosy and big enough for two people. You have everything you need.
Also it was very clean and tidy.
The metro is close to the apartment and many restaurants too. (Very good: La Crepitante)
If we travel again to Paris, we would choose Ruth apartment again.
