I come to Paris twice a year. This is the best accommodation I have ever booked. It is adorable, quiet and charming. You have complete privacy. There is cable television which is easy to use, the wifi is fast and dependable. The Metro station (Chevalet) is a block and a half away. There are several shops and bakeries nearby. You are also steps away from the River, the National Bibliotech, and beautiful Park Bercy.
For a true Paris experience outside of a hotel, this can't be beat. Karine is a wonderful hostess and this apartment is worth every penny.
