I enjoyed my stay here during my trip to SF. Check in was easy, they were nice to hold bags before checking in and out, and the location was great. It was easy to use public transport to travel to/from the airport as well as to get around the city. The shared bathrooms worked well and it was always furnished with shampoo, body wash.
It may get loud outside due to being on a major street in downtown. There were homeless people on nearby streets, but I did not have an issue walking around the area and the hotel entrance was clean.
Overall, nice place to stay in SF!
