I cannot recommend Mel + Pat's place highly enough. For context, I stayed here for an eight-month period. Here are some of my favourite things:
1. The location is great. You are walking distance to many of the tourist attractions and historical sites the city has to offer, as well as to grocery stores and pharmacies. The neighbourhood is very safe. The Université Laval and VIA Rail station are both short bus rides away.
2. The apartment is beautiful. It is bright (great for plants!) and has beautiful wooded trim/borders. Functionally speaking, it also has everything you need for a short or long trip: an absolutely complete kitchen, washing and drying machines, etc. There is a small balcony at the back with a patio table and chairs - there is a beautiful tree and the entire area is very peaceful. Also, during my stay, I don't think I was disturbed by noise once. I never heard them speaking downstairs (they live just below the apartment), and could only occasionally hear the neighbours speaking (not loudly, mind you!) in the stairwell.
3. Finally, and most importantly, Mel and Pat are lovely people. They are very accommodating and helpful. They responded to every one of my questions/needs/requests very quickly and politely, never making me feel uncomfortable, but they were also able to give me my space. They never imposed but also managed to be constantly friendly/neighbourly. It was a perfect balance for me, and I am sure they strive to accommodate all of their guests.
