We - my husband, son and his girlfriend - had a marvelous opportunity to stay at Jacques' place for three days in the very, very heart of Paris. We felt welcomed and our stay was really comfortable and cozy. The flat is small, but so nice. There is everything you need to feel good - fantastic view over the Paris rooftops when you are having breakfast, comfortable beds, perfect shower (without any problems with water in spite of the six floor), excellent zone of kitchen with main necessary equipment, free internet. Even espresso coffee and coffee machine and you can make quick coffee after arriving. Fantastic neighbors Patrick and Dominic are so helpful.
I even don't tell about perfect location in all meanings - the place is next to the Pompidou Center, excellent transportation from the CDG Airport, small walking distance from many sights of Paris.
Besides everything - immediate response from hosts, answers to all your questions.
Have plans to go to Paris - just write to Jacques and your accommodation problems will be solved! THANK YOU, Jacques! Probably we will come back some day!
