    A good stay in Union Square area

    The hotel is located conveniently to Union Square shopping and is a short walk to the Moscone Center. The rooms are showing a bit of age, but are comfortable. The chaise is a nice addition for relaxing after a long day at work. The staff at the front desk, the doorman and the staff in the lounge make this hotel a really nice stay. They are friendly - every day when I came back to the hotel, the doorman welcomed me and asked if I had a good day at work! There is a $30 daily destination fee, which is very common in San Francisco, and you can use that anywhere in the hotel. The only slight negative is the small restaurant/bar in the reception area. It is decent, but if you are stuck spending the $30, for several nights it gets a bit old, not bad, just repetitive.I have stayed here a couple of times recently and certainly intend to come back.

    First night check in

    Had a late arrival, checked into the room, within 10 minutes security came to my room saying we were being loud. Apparently a noise complaint from the floor below because we were unpacking the bags. First impression, not good. These walls are thin and the rooms are small. There was no water in the room and I had to go back downstairs to get water. The A/C barely function well.

    Accessible Hotel

    Overall, we had a wonderful experience at Marriott Bonvoy in Union Square San Francisco. Not only was the location convenient and easily accessible, but the staff were also incredibly helpful and friendly. The room itself was spacious and clean, providing a comfortable and enjoyable stay. We highly recommend this hotel for anyone looking for a convenient and pleasant stay in San Francisco.

    Best Marriott I've Ever Stayed In

    Hands down the best Marriott property I've ever stayed at, and I've stayed at A LOT. I could not get over how excruciatingly kind ALL the staff was...from the bellman, to the front desk staff, bartenders, breakfast staff, to the housekeeping...everyone genuinely made the effort to speak to me, give me suggestions, ask me how my day was going, and smile. I don't know what they do to train these employees, but this property needs to be the benchmark for all hotels. The Hotel was conveniently located, clean, and quiet.

    heartfelt hospitality by staff

    Justine and Roy at the receptionist desk helped me much for booking a taxi to San Francisco International Airport at midnight of 15 Dec. 2023. Their heartfelt assistance was very helpful, and made me very happy. Also, during the whole period of my stay, Kelly at the reception desk, and a doorman Fernando helped me very much. I really appreciate their heartfelt assistance.
