I stayed at Lola's for about a week, and it was fantastic! The apartment itself is super clean and has a lot of character with the wall art. The amenities were great and the host is professional and very on top of communication, making the check-in very smooth.
The location is really nice -- it's not precisely central, but you can easily walk to many fun neighborhoods with restaurants and bars, making it easy to explore the city. You can even walk to the old port in a little under a half hour (or less than ten minute drive / cheap Uber).
I highly recommend this place and would definitely stay again next time I'm visiting Montreal!
