The concept for Sonder is really interesting. Well appointed, well priced efficiency apartment/hotel room with a virtual front desk. The technology required was quite smooth, even for someone of a certain age like myself. Great location and amenities right down to the sharp kitchen knives and mini bottles of olive oil should you feel like doing a little cooking (we didn't). The only issue was that the walls were paper thin and you could hear sounds from the adjacent rooms. However they do supply sleeping ear plugs and a sound machine.
