We stayed 4 nights at Guillaume's apartment and we were very comfortable there. The location is absolutely unbeatable. On the first line of the river Seine and with the view towards the Notre Dame Cathedral. Apartment is bright and decorated in a simple way, but with a good taste. Contact with the owner was quick and very efficient. The only details that we were missing were some kitchen utensils like for example knife to cut the bread or corkscrew and some broom to keep the floor clean during your stay.
