We had a very pleasant stay here in July. The room was small, but very clean and comfortable. Good shower, comfortable bed and friendly folks working the front desk.
The location is great, a couple of blocks from Notre Dame and the Seine. We didn't do breakfast at the hotel, but there is a wonderful bakery just around the corner. There are several small markets nearby with great produce (everything you need for a picnic).
My husband and I were able to walk everywhere, but the metro is very close.
We drove into Paris and parked the car in a garage right across the street from the hotel for the three days that we were there (I did reserve that ahead of time).
We would definitely stay here again. You simply can't beat the location/value/convenience.
