We paid for 3 nights for 3br place. Due to a power outage in that building, they put us up in a smaller, 2br place with a pullout couch. We had 3 different parties, so we needed three separate bedrooms. Nobody got any sleep on the pullout. We asked to move to a 3br place, they said they'll get back to us... but never did.
Sonder told us they'd refund the difference - but they didn't tell us what the price difference was. In the end, they refunded less than 10% of what we'd paid for the 3 bedroom after I messaged them about it.
