We had a really pleasant stay at Karine's apartment, and she was very hospitable and friendly. The flat was nice, situated in an old house that had it's own special atmosphere.
The apartment there is well-decorated, comfortable, and has almost everything you may need, although it's better to take your own hair-drier and to wash the dishes before using them. :-)
If you go with your friends, like us (2 couples), may be it'd be useful to know that there is no door separating one of the rooms from the hall, only a curtain. ;-)
What is just brilliant is that Karine provides you with a folder which contains a lot of useful information about the flat, the quarter, some restaurants etc. We've really appreciated it!
The quarter itself is also rather nice, specially in the mornings, although I wouldn't recommend you to walk there late at night as we did once and were made to feel rather uncomfortable... But anyway, we had a good time there.
