This stay was beyond perfect. It is a 4 floor walk up, which will give you the exercise you were looking for! We loved every single minute of our stay--the beds are super comfortable and clean, and the living space and kitchen on the second floor are extremely spacious and lovely. When we had a question about the water heater, Bertrand responded immediately and we solved the issue in no time. Thank you--we'll be looking to stay here again next time!!
