We stayed in Christophe's Place for 5 nights during our trip to Paris for our 10th anniversary.
The house is in a fantastic location that has access to 3 different metro lines within 3 to 10 minutes walking from home. The neighborhood is beautiful and perfectly safe and it is near a lot of central touristic streets that provide everything to the visitors.
Also we found the house extremely quite during night hours.
The temperature of the house was ideal and we didn't feel any discomfort during our stay in Late September.
In general it is a small cosy house with basic amenities like WiFi, TV, Hot Water etc.
We live in a big house so fitting into a Parisian flat was a challenge on its own.
On the cons side the flat is on the third floor and there is no elevator so it was a bit challenging to walk up with the suitcases plus the stairs are very narrow and can be slippery.
Also due to the fact that the bathroom has no windows or ventilation, the house can smell moldy if the windows stay closed for too long.
Our biggest problem was that the bathroom door would not stay closed or lock. It was not our best moment when one had to "go" since the other person had to go in the bedroom to avoid an awkward moment.
The bed was ok but a bit hard for our taste.
Also as we have high standards regarding cleanness we though that It was not dirty but there where margins for improvement.
Finally the TV decoder was fried and also a couple of light bulbs too. That left us with a bit of bitter taste since we felt the house was kind of neglected.
Our stay in Paris was fantastic and the house location helped a lot in that.
I am certain that since Christophe is a very responsive and kind host he will do his best to address all these minor issues.
