We were so impressed by Le Damantin. The staff were all and I mean ALL, really friendly and helpful. The room was clean, well arranged and lovely decor. The food was really good at every meal. We couldn't be bothered to go out for dinner our first night so ate in the hotel, and it was so good we dined in another night instead of going out. The hotel is really conveniently located, just a 30 minute taxi from Gard de Nord and easy walking distance of several sites of interest. The weather was lovely so we walked everywhere instead of getting the metro. We would definitely stay here again. The only slight negative was that our room window was over the courtyard and one night some (rather embarassingly, English) guests were being very loud until 3am, so perhaps a room with a window facing the street would be more guaranteed to be quiet.
Otherwise we couldn't fault the hotel at all.
