Could have been a great stay but the lack of support when things went awry made it an uncomfortable experience. Starting with the positives, the room was clean and simple (though we did notice a few unpainted surfaces), well located, with easy check-in and access. Downside was the in-unit AC was down on an unseasonably warm weekend in Montreal. Room was close to 30 C/80s F., which was too warm for us to sleep comfortably. Sonder tried to send someone to fix it but could not. All would’ve been water under the bridge had they not made it impossible for us to cancel the remainder of our reservation and find new accommodations. Unreasonable to expect guests to stay and pay for accommodations under these circumstances. Thankfully AirBnB stepped in and we were able to cancel our last night there, but only after two nights of bad sleep.
