We enjoyed our stay in the apartment in Burlingame. I hope by now Blueground have worked out the problems with their check-in procedure. When we checked in in December, the entrance code, which was supposed to have been emailed to me by a third party, had not been emailed to me. So there we were in the dark and cold, unable to get into the building. I had requested an early check-in and was denied, and so to then have that experience of not being able to check in during the prescribed hours was frustrating. And no Blueground employee could get us entrance to the building that night, though they did offer a night in a hotel. The rest of our stay was fine, except for the flooding during torrential downpours (twice) and the elevator not working for most of our stay, and we were on the fourth floor. However, those were problems created by the building management, not Blueground, and Blueground was responsive to communications.
