We are aged in our mid-twenties and we enjoyed our experience with Sonder. We didn’t experience any problem entering the building unlike some reviews I read. No staff in building, code entry into building, elevator and room. Mobile key is optionable and I liked that feature. I could see how it would frustrate older guests. There are privacy blinds and curtains in the room, unlike someone stating it was kinda see through curtain in a previous review. Clean and comfortable and great location!! The Peruvian restaurant next door was delicious as well.
