First off, Yan was very responsive and clear in his communications, especially his check-in instruction via PDF.
As for the place itself, it’s clean and spacious enough for 4 people (or two couples). Parking is just across the street and appeared safe. Overall, very satisfied with the stay!
As for the location itself, you are approximately 1-5-3.5km walk to just about every major tourist-y attractions: Plains of Abr’, parliament building, chateau Frontenac, Notre Dame, and general old Quebec/downtown area. You can do a big loop via walking and pretty much see everything under 3-4 hours.
One quick recommendation for breakfast/general starting point for your trip: go to Bügel Fabrique de Bagels (164 Rue Crémazie O, Québec, QC G1R 1X7) - what a fantastic breakfast/bagel place. From this point on, go to plains of Abraham then parliament and so on. Have fun!
Great place. Great stay. Great host!
