You will experience classic J.W. service throughout the entire hotel with each and every staff member that you encounter. The hotel lobby was quite packed upon arrival and yet the front desk staff worked expeditiously to make sure all guest were serviced as quickly as possible. The accommodations are first class and almost taken for granted since this chain offers... More

I've just returned from a 6 day stay. Re-reading the reviews here in TA, it is extraordinary how different the opinions can be from one's own. I found the hotel excellent on almost all relevant items. Staff is fantastic, from porter to cleaning lady. Mattress was wonderful, TV was a 42" flat screen Samsung with HD channels. Bathroom had great... More

This hotel is only a block and 1/2 from Union Square right in the middle of The City. There's nothing particularly special about it (it doesn't have a spa) but for San Francisco you can't beat the location for the price. Great service from the staff.

If you approach this hotel from public transportation running down Market Street, prepare to walk up one of the hills San Francisco is famed for. It sits on the border of the downtown shopping area, near Union Square and expensive stores such as Cartier, Burberry, Gump's San Francisco and Saks Fifth Avenue. The hotel also is located within walking distance... More

This hotel is perfectly located a block away from Union Square. It has wonderful staff, a very nice lobby and lounge area, which unfortunately is on the 3rd floor. You have to make a special trip to walk through. This is more unfortunate than one would think. You would probably be using the elevator to get there, but we weren't... More

For some reason beyond me, hotel management has eliminated those ubiquitous single cup drip coffee machines from all guest rooms and replaced then with fancy chrome espresso machines and tiny espresso cups. While the hotel offers 24 access to the concierge lounge, coffee is only available upon the official openning of the lounge at 6:30 am. As a traveler from... More

Large hotel, a block off of Union Square. But, it feels like a haven from which to operate. Great lobby, with free wifi, coffee, tables and seating arrangements to just hang out and plan your visit. Very helpful staff and concierge. Just a block from the cable cars. We had a blast exploring the city from this hotel, and the... More

In booking my reservation, a mistake got made somewhere along the way and it ended up being a day too short. Most likely my fault -- this I acknowledge. I asked the front desk if I could extend it and the answer was "yes, at a nightly rate of $644". That was more than twice the rate I was paying.... More

This hotel is the best location in San Francisco. Just off Union Square near all the great restaurants and theaters. The rooms are very large and the bathrooms are luxurious. It is our first choice when visiting San Francisco. Great concierge lounge.

Staying in Union Square

Neighborhood Profile
Union Square
Originally home to rallies supporting the Union Army in the Civil War, this grand square has become the city's premier shopping and entertainment district containing the largest number of upscale department stores, chic boutiques, art galleries and theaters in the city. It's a large open area where tourists and locals gather, watch cable cars and crowds go by, enjoy a snack, or plan their day of shopping and sightseeing, If feeling the pulsating energy of the city is on your agenda, Union Square is the place to soak it in.
