The hotel is very quaint and in a more quiet setting away from crowds of tourists. Within walking distance are numerous cafes and cute little shops. Dining options are plentiful in the neighborhood and the Michelin-rated Christine Restaurant is right next door (not affiliated with the hotel). We had lunch at the restaurant and it was above average with reasonable prices for the area.
The hotel staff were accommodating and responsive, which is to be expected of a 5 star property. I typically compare the level of service received at 5-star boutique hotels to the service I would normally expect from any Four Seasons or Ritz Carlton properties. The service and amenities at this hotel were adequate for its size, but I would not classify it as beyond reproach. The hotel is very small, so do not expect an opulent or grand lobby. We stayed in the duplex suite and the size of the room was rather limited, but pretty consistent with Paris standards. Small touches in the room were nice, such as towel warmers. If you are looking for old world charm away from crowds and personalized service, the Relais Christine is a decent option. However, if you are looking for a more social and vibrant atmosphere, I would stay elsewhere. All together, we enjoyed our stay and would come back.
