Check-in was quite seamless, the apartment served its purpose and was centrally located, but will not book again.
The apartment was very small, was quite cold and the heating did not work. Overall, it had more the feel of a hostel than the described hotel room.
Furthermore, this started on the wrong foot, as I nearly had to cancel my trip, but would have had to pay over 75% of the booking, so found a way to make it work. I had not read the cancellation policy when booking, but found quite restrictive and will likely avoid Sonder going forward.
