The Sonder was very close to where I needed to go, Vanderbilt Medical Center. Good location. Room was very clean. All the codes needed and getting them to work was not good as the instructions weren't quite clear, such as using the palm part. Also, once I parked, a sign read "you must have a parking ticket to gain pedestrian access back into building." After 25 minutes, I finally had someone wait inside the door when I went out to see if I could get back in, which I could. Maybe it meant after 11 pm? Have no idea. Several people tried to help me get elevator code work as I rode up and down. Finally, it worked.Again, I appreciate the location and cleanliness, but this will be my last time trying the Sonder.
