I had a very restful 2 nights at Sonder Arlo.
I arrived too early to check in, but I was able to do some work in the lounge, and then use the gym. By the time I was done in the gym, my room was ready (early check in) so I went straight up to have a shower.
I really appreciated being able to check in when the room was ready, rather than being told that I still have to wait until 4pm.
The kitchenette was great for making meals, and the bed was very comfortable.
I do have a suggestion though: shower robes would be a great addition to the room, especially at the price point.
