Catherine is GREAT! She organized everything well. We were met by Sylvia and Stephan, explained everything. Catherine's studio is lovely place, enough for two and it has everything for every day life. Quiet place in a beautiful district, 40 mins on foot or 3 stops by rer and you are near Notre Dam. RER B is very close and it is very suitable, especially from CDG and back. A lot of restaurants and bakeries around, what you need more. Want jogging - Luxembourg Jardin is a step away. We really enjoyed.
