Reynald is a very kind and helpful host. We loved him. He is an easy guy to deal with.
As for the place itself, do not worry about air conditioning. We visited in the hottest time of the year (July) and we had no problem even during mid-day. The bathroom is a bit odd as it doesn't have a proper mirror so I couldn't shave my beard easily. The place is a basement and a bit small for 3 people. The kitchen is very well equipped.
