We’ve had an excellent stay at Sonder on Rue MacKay in August 2022. There was no construction nearby. The nights were actually pretty quiet. We came with 2 kids and they slept just fine. The location is amazing as it’s close to everything. We enjoyed Myriade cafe on the first floor and Pigeon coffee (3 min walk). There is also a grocery store on the main floor where you can get water. McDonalds + other restaurants are literally 3 min away. We were on 9th floor facing Concorde parkade area (that stops operating at midnight) so the area was pretty quiet. You can open all doors with a special 6-digit code you are given. There are no actual keys. It’s much easier to use Sonder app and open doors with a mobile key. We’ve used this mobile key instead of entering that code (you have to enter it 3 times - main door, elevator and your room, and it can get tiring). But love the security of that building! I didn’t mind using Sonder app at all. It was convenient. The service was amazing. I had a small issue at 2am (I didn’t know how to unplug a sink drain -hint- you just press on it) and they replied to me at 2am!!!! The service was very prompt and Sonder was amazing at communications. The extra towels I requested via Sonder app were delivered in a nice branded bag. The quality of service is definitely there. The apartment was very nice. The balcony is massive. The terrace on the 20th floor is stunning + lovely lounge and pool terrace on the 14th floor. The pool and hot tub have weird hours of 12-4pm so that wasn’t convenient for us at all other than for one afternoon but overall we really enjoyed staying at the apartment and would go back there again! The staff was very pleasant and helpful. Opened the main door for me many times when they saw my stroller and even held the elevator door open for me multiple times. I am very pleased with Sonder, and I think that the service was equivalent to a 5-star hotel. Also, great area for Uber eats deliveries and catching Uber rides. 10 min drive to the old town, 5 min to the Montreal Forum, 3 min walk to Saint Catherine street, 7 min walk to H&M and Holt Renfew + other shops, 5 min walk to Crescent Street, 11 min drive to St. Joseph’s Oratory and also, 3 min walk to an overnight 24-hour parking (Just use any map app and go to PROPARK on rue MacKay - it’s next to Structube on rue Mackay) where we parked our rental car. You can’t park overnight in the Concordia parking lot that was facing our building. But we parked there for a few hours when we wanted to take a break. For street parking, I recommend downloading Montreal parking app called P$ServiceMobile. So easy to pay via the app. Perfect place to stay in Montreal!
