If you want to have an experience in one of those old French buildings, and the neighbourhood, then this is the place.
About the host: Guy has been very patient, friendly, and organised. He is such an energetic and cheerful person, and he is a very talented artist. I also like his music. And love his expresso! He is the best!
About the location: relatively a little remote from main attractions except Monmatre. But Paris is a city where you can get around within 30 minutes by metro, so no big deal.
About the room: I have to mention two things for others who are interested in it to take into account. Firstly the room feels cold still even the heater is fully on in February time. Secondly, lack of privacy. The door cannot be locked, I can see that Guy has helped make the room, which is very nice and responsible of him, and turn off the lights when I forgot.
In spite of that, the room is extremely quiet! Very very very quiet and sound, very cozy. Small but comfortable. You can even do meditation without any problem.
You will have free time schedule of your own here, which is a plus.
Therefore I recommend this little beautiful place to the whole community.
