We really enjoyed staying at Isabelle's place, and Isabelle was very helpful before and during our stay.
The location was perfect for us - close to lots of restaurants, bars and shops, and not far from the main sights. Isabelle gave us lots of recommendations for places to eat (don't miss the tarts and cakes at Maison L'Amour). The square down the street was very buzzy with live music at the weekend and it was lovely sitting on the balcony in the evening.
The apartment is small (the bed is a sofa bed), but nicely decorated and very comfortable. We liked having the small kitchen so we could make breakfast in the morning and light meals.
