The 4 of us had a pretty good time at Francois place in July . The studio is located about 3 min walk to the metro station and there are a lot of options to eat and chill out in a 500m radius.
The hosts live on the ground floor and our room was on the upper level. There are 2 big beds and one bathroom for guests use. We thought this was pretty good value for the price so close to Paris.
Francois was very efficient in replying to emails and always seemed happy to help.
The only minor issue we had was the noise from the streets late at night. Close the windows and use the fan when it gets hot is our advice.
All in all we were quite happy with the place.
