I am writing this note in order to acknowledge the superior level of guest service that was provided by Antonio at the San Francisco JW Marriott Union Square (front desk). I was a guest during Oct. 6 to 10th. Antonio delivered a level of service, understanding, and sensitivity to guest needs that was unsurpassed by none I have seen in... More

Stayed here for 3 nights at the end of September. Good location within walking distance of the main shopping district, Chinatown and Little Italy. The hotel itself was great. The rooms were spacious, clean and well kept. The staff were also very friendly and helpful. An enjoyable stay and would reccommend to others

Was here on business near Union Square and this was typical, solid Marriott experience. Rooms are newer than many in area and large. Club lounge for Marriott Elite members is far too small and I continue to be annoyed that they charge $10 for a "free" glass of poor wine. Otherwise food good, staff nice and location is great.

The staff @ the JW in San Fran was fabulous and accommodating. They went out of their way to make us fell special for our anniversary. We will definitely plan our next stay when we visit San Fran in the future.

We are on a road trip staying at several hotels along the way from LA to San Francisco, our room at JW Marriott is the best so far. When you arrive at the main desk the rooms are... More

I stayed at the JW Marriot for a quick weekend trip for business. The hotel room itself was very nice with the most amazing bed - honestly, one of the most comfortable hotel beds I've slept in. I woke up so refreshed each morning. Most of the staff were very pleasant as well, with the exception of one of the... More

Very nice hotel - convenient location - can walk to the Union Square shopping and many wonderful restaurants. My room was great for a business traveler: Roomy desk with many outlets and good desk chair, outlets conveniently located next to the bed. My bathroom was well appointed and had great water pressure in the shower/bathtub! Service was excellent. Valet for... More

This hotel is very nice. Rooms are clean and spacious. Stayed at a 55Parc earlier in the week and this was much cleaner and up to date. They have a nice fitness center with free same day laundry for your workout clothes. The rooms are roomy, modern, and clean. The staff was very nice. Marriott rewards customers get access to... More

Neeraj and the entire team at the JW Union Square make the difference. As frequent business traveller this level of service makes all the difference in the world. This is my go to Marriott every chance I get. Rooms are clean, beds and pillows are great. But the team here makes the visit like coming home. Always warm and welcoming.... More
