We had a wonderful stay at Guillaume's place! He was very accommodating, made sure we had everything we needed, and was very fast and easy to communicate with!
As for location, I'm really glad we ended up
staying here in Montmartre. It is next to a bunch of great places to eat and off of a more pedestrian street.
We arrived during a heat wave, and I was very surprised at how cool it was in the apartment compared to outside. It still wasn't great during the heat wave without air condioning since the natural conditions of the apartment can only do so much, but on most days it was a comfortable temperature!
Overall we loved our stay, and especially appreciated the host!
