The unit we stayed in was very nice and clean, however, the check in process was extremely difficult. Sonder requires you to download an app or use their website to complete the check in process. One of the requirements is to upload a picture of your ID and to do a face scan. I have my drivers license already uploaded to Airbnb. I tried taking the pictures on both my phone and laptop. The images looked crisp and the devices have a good quality camera. I had to upload my ID and scan 4 separate times. They will also not send you the check in instructions until this step is done.
As I was on the way to the train station, I opened the app to look up the check in instructions. I could not access them because the ID and scan was not accepted after 4 separate uploads. I used the chat function to chat with a rep from Sonder. They said the check in was not completed because the pictures looked blurry (from my end on both my laptop and phone they did not) or that the credit card and ID names were different (they were not).
The representative said she did not have access to my booking, which was very stressful because I was on my way to Montreal then for a work conference. She suggested I contact Airbnb. After some frustrating back and forth messages with Sonder and Airbnb I was eventually sent the check in instructions.
Overall, I would have stayed in a not as nice place if it meant I didn't have to panic on the train thinking I didn't have an Airbnb that I have paid a lot of money for. Also bumped into others outside the building that were struggling to check in as well. Will not be staying with Sonder again, and I would HIGHLY suggest that you don't either.
