We did not meet Céline but she arranged for us to get keys from the doorman of the building and she gave us lots of tips for restaurants around her area. She was so kind as to let us keep our luggage in her apartment past checkout time for convenience, and kept in touch with us to check whether everything went fine.

The apartment is cute and really nicely decorated! Céline has a stunning cookbook collection ;)
However, travellers with a light sleep, watch out: as Céline says in her description of the apartment, it is located in a small street full of bars so it gets really noisy at weekends! (cannot say regarding week nights as we were there on a Saturday)
