Im Sure All Sonders Are Different. I stayed at the 16th & Chestnut one in Center City, Philadelphia.
The Pros: Location! (Unbeatable). Your own private apartment. (In these times of Covid-19, having an actual kitchen and a washer & dryer was indispensable).
The Cons: The building is old! (Every time I showered the tub filled with water and I needed a plunger to empty it). The sensor-locks! (I sat on the floor for 3.5 house because my door lock had a dead battery. Finally, Sonder offered my an upgrade for the inconvenience. The lock worked fine, but they are finicky ... sometimes it would take several attempts to get in). AND speaking of the upgrade, Sonder asked me to return to the original apartment after they'd fixed its keypad claiming my upgrade wasn't clean. I'd already unpacked everything and was exhausted after waiting 9 hours to check in ... they have no luggage storage; that's an extra cost and a mile away ... I refused to move after I'd unpacked. I was promised some kind of coupon or gift certificate or the like for these inconveniences, but I've yet to receive them.
Not Sonder's fault: its guests! Not one of them wore masks and the elevator in the building is small. I refused to let them in with me. Also, one family chose to let their children run up and down the halls to play since they couldn't go outside and their screaming was impossible to deal with.
Prognosis: There is a lot of promise here, but this property isn't there yet.
