The location of the Airbnb is very good. The hotspots of Quebec are all in walking distance. Oliver was very friendly and answered very qucik to my question. The Airbnb itself is quiet new and we all felt comfortable inside. Everything was clean. Oliver even prepared some snacks, coffee and water for us. For those who like to cook, there's enough equipment to do so. All together this was a 5-star stay.
Anyway there are some critics: It was very cold when we arrived, especially the bedroom in the basement. The pictures of the living don't match the reality. It is way smaller and the big grey couch is not in there. The laundry dryer didn't work. Important: we didn't have two full bathrooms. There is one full bathroom with a toilet, shower and bathtub upstairs but the bathroom in the basement is only a toilet - there's is no shower. Therefore, we only had one shower for seven people.
Still we had a great time in Quebec and were overall very happy with the Airbnb.
