Very enjoyable stay! Fabienne's flat is a ten minute walk from Gare du Nord on a quiet side street. I wasn't disturbed by noise when I was there and it was quite cool even though it was very warm in Paris when I visited. It is quite small but cosy with a good shower and comfortable bed. The toilet is in the corridor but I think only guests ever use it. The flat is on floor 6 but there is a lift so if you have heavy bags not a problem. I am planning to go back to Paris in the near future and would definitely stay there again if available. I didn't meet Fabienne but she seemed very nice and all communication was very fast, thank-you Fabienne :)
