I book a spacious studio with sofa and balcony under Sonder for a week thinking we'll be able to spend our Christmas in a nice unit. Without any notice, they changed my room to a studio that is very different from the one I booked. It was a lot smaller, no sofa, no balcony, just a small window without even a view of the city (what you'll see outside is just windows and walls of other units).
When I called them to complain about it they told me that all the units with the balcony are under renovation. But looking from outside, it doesn't look like there are units with balcony on that building (this is Sonder along Canal). Anyway, I was very disappointed cause I was not informed about the changes and it felt like I didn't have any choice but to stay cause it's a hassle to look for a new place to stay for a week. They refunded an amount to me since I complained but the expectation of being able to stay in a nice and spacious place for Christmas was definitely compromised.
