We had a great stay, the location was perfect, the place was clean, tidy, comfortable, nicely designed and very well equipped (though a small bin in the bathroom and on the upper floor would be an improvement).
I would definitely recommend this place and will dream of returning soon again!
Leon was very kind, but keep in mind that check-in and out is done in person, so better arrange a time in advance so that you don't have to wait.
Thanks for a wonderful stay in Paris, we will be back!
