We have stayed here before and had a very nice experience, however our most recent stay was not satisfactory. I am disabled and have mobility issues. We were told upon arrival that the elevator was broken and that our room was on the third floor. The person at the front desk although pleasant, gave us no option other than climbing three flights of stairs. My husband pushed for a better option and finally we were told that we could have a room on the second floor, which still meant me climbing two flights of stairs with limited mobility and a cane. The first set of stairs had no handrail and I nearly fell several times. After we finally arrived at our room we discovered that we had been assigned a room with 2 stairs at bathroom entrance. We were surprised that front desk person saw how much I struggled and still put us in a room with steps at the very end of a long hallway. Even being as cautious as possible I fell on the steps that evening. We tried to discuss issues with front desk person again and were told that it was out of their control. We had plans that night and the next morning which meant climbing two flights of stairs multiple times. It was truly an awful stay.

The location is excellent for this hotel, my wife and I stayed there during the Thanksgiving holiday of 2025, and we were both excited about touring and sightseeing the beautiful city of San Francisco Upon arrival we were greeted by the front desk person which was very cordial, but at the end of our check-in, she said she had bad news for us, and the bad news was that they’re elevator was not working and more than likely would not work during the duration of our stay. We were originally set to have a room on the fifth floor, but as a person with two knee replacements, hiking five floors to come and go from a hotel room is a little bit of a challenge. I immediately asked to be upgraded due to our inconvenience and be placed on a lower floor, which they were able to accommodate. The room was spacious clean well kept however our showers water pressure was very, very low and it struggled to get hot enough. The non working elevator actually hampered the comings and goings as having to climb stairs (narrow staircase, and in one area, a short ceiling where I bumped my head twice) to come or go from the hotel room to do anything was work. Overall, my wife and I still enjoyed San Francisco, but it wasn’t our ideal trip and I hope that the end that you square does resolve a few of these issues so that future guests won’t have these inconveniences to disrupt inconvenience their vacation.
