We had a fantastic time at Guillaume and Fanny's place. The house is very large and spacious, and there was lots of space for the kids to play. The beds were comfortable and everything was lovely and clean. It's on the second floor so there are several steps to go up, but that wasn't a problem for our family.
Fanny had some helpful local suggestions for dinner when we checked in and they have an online list of recommendations as well. We'd absolutely stay here again the next time we come to Quebec City!
