We loved staying at Mendy's place in Montreal!! The close access to transit made navigating the city very pleasant. The wifi was fast and consistent. Check-in was seamless and we had everything that we needed for a week-long stay. The place was impeccably clean and we really enjoyed the water pressure :)
I will agree that we were able to hear activity in the upstairs unit early in the morning on weekdays, maybe 8am, but we are early risers so this did not bother us.
We found the unit to stay pretty cool and comfortable, despite the warm temperatures outside (up to 80s). We did get a little warm some days, noting that there is no A/C at this place. Mendy was communicative and a great host. Would recommend!!
