This apartment is great! The pictures don't do it justice! It is clean, spacious, and comfortable. We spent four nights here with our two children, ages 8 and 11, and it was the perfect size for us to hang out in during the morning and evening. We ate breakfast every morning on the porch, which was very pleasant (we visited in August).
It is an easy 20-25 minute walk for able bodied adults to the touristy Vieux Quebec area. However, since it's an uphill walk, our 8 year old was a bit worn out by the time we got to the old town. We took an Uber at least one way, which was very inexpensive i.e. US$6.00 one way. The neighborhood where the apartment is located feels safe and there are good restaurants within a 5-10 minute walk of the apartment. There is also a supermarket and cafe/bakery within 5 minutes walk of the apartment.
Yves and Marie were very responsive and communicated promptly with us. We would definitely stay here again.
