I had a great stay at Catherine place. It was only 15min walk from the montmorency falls, so I could go with my family and my baby on the stroller and had a nice picnic day. It was 20 min from quebec, which makes it the perfect place if you want to do some tourism at quebec city and montmorency falls.
Catherine and her husband are great hosts, they even provided a small mattress and blankets for our 10 month old baby, in addition to all the blankets and towels we had. The kitchen is well equipped and they provide everything you will need for a short stay.
We will look again to stay at her place when coming back to quebec.
