The rooms (2 Queen beds) were very small. There was almost no water pressure in the shower, and when the hotel staff was contacted, they said they would send someone up to check it out, and this never happened.

I had bugs (mites) in my initial room. I was transferred to another room.

Many homeless people on the streets. I booked a big room and when i checked in the person told us she will upgrade us to a better room and gave us a small delux room. Because We are on a short vacation I don’t have time to make the issue solved. Checking in area was very noisy you have to shout at each other to hear. Our room ventilation has thick dust. The hotel needs improvement its old the carpets needs to look clean.

The only real complaint that I have about my stay is that the floor, the entire floor, reaked of weed. I know it is legal but it took away from the experience. The room was nice, the bed was comfortable and the staff was friendly and helpful. The property was beautiful.

Disliked: Staff & service
I had some bitter taste when I was charged A LOT for an urgent international call with their room phone. The rate was not provided anywhere and I was expecting a higher than normal charge. But when I saw the charge to my credit card, I was shocked.

This property boarders the really dirty drug infested area of San Francisco. May have been nice years ago, now you see needles and feces on the side walks. Find a more affordable clean destination in the us.

6/10 Okay

Not much to like, just an average place. Self parking for 3 days was $310 Wow! Poor signage in the garage, even the workers at the front desk said it was bad. Next time its AirBnb!!!
