I stayed with Celso for 9 weeks as a solo female traveller and I truly enjoyed my stay. The apartment is spacious with lots of amenities and an incredible view of Mount Royal. My roommates were super nice and very helpful as I was new to the city and wasn't familiar with the area.
There are several grocery stores and pharmacies just a few steps away and it was really convenient that public transportation was very close as well.
I would definitely suggest this place for anyone looking to stay on a residential street close to downtown.
