The hotel is ideally located, I really couldn't have asked for a better location - very close to many restaurants and cafes, the little "village square" where they had a christmas market set up, as well as many local historical sites. There are about 3 metro lines within walking distance and many bus routes, making it a great home base for seeing and accessing the rest of Paris. Be sure to give yourself at least a full day to explore the surrounding neighbourhood, it has a rich history and so much to see just within a 10 to 15 minute walk of the hotel. The front desk staff were friendly and very helpful.
The rooms are TINY. They fit the bed, cabinet, and that's about it. But it's Paris, so that's really not unusual and will be the case for almost any boutique hotel you book. I stayed 6 days with a carry on luggage and I think had I been staying longer or had a full size luggage, I might have found the room a bit too small. The room was clean, the bathroom was clearly newly renovated with great water pressure etc., and the view from my little balcony was just lovely. The rooms/hotel are nothing special in terms of decor or ambience, so if having a very aesthetic hotel is important to you, this won't be it. But if location is king for you, I would highly recommend it as a great (and affordable) option.
