My adult daughter and I stayed at this apartment for 4 nights in mid November. Kat was very friendy and helpful. The location is wonderful. I would recommend Kat's place to anyone interested in a authentic Parisian visit. Yes, there are 60 stairs. If you have any limited mobility this would be a problem, but it was fine for us. After eating so many wonderful things, it made me feel a little better to burn off a few calories! The second sleeping area is a loft, so there are also stairs involved. I slept in the bedroom, and it was fine, but my daugher said the mattress in the loft was not very comfortable. All in all, it was a great experience.
