Profile: Union Square

Profile: Union Square

Union Square has an upmarket, European feel, with well-heeled shoppers drifting through monolithic department stores and luxury boutiques in one of the world’s foremost shopping districts. Prada, Burberry, and Louis Vuitton all do a smashing business here. Many of the restaurants offer open-air dining and eclectic, world-spanning menus, running the gamut from Californian-Indian fusion dishes prepared by a Michelin-starred chef, to Italian-style pizzas enjoyed around communal tables.

In the winter, the square’s a popular spot with native Californians who make a pilgrimage to see the giant Christmas tree and outdoor ice skating rink. Union Square’s theater district is also worth a journey, as it’s home to the famed American Conservatory Theater.

    Excellent property with a wonderful atmosphere. Everything perfect except transport to airport was made on the wrong day which left us with a stressful ending to an otherwise perfect stay.

  • 10.0.Exceptional

    Love love loveeeed this hotel! I always read reviews online before I book things, especially when they are as pricey as hotels in SF. The reviews weren't great for this place which made me nervous, but from the moment I arrived I was so glad I made this choice. I'd like to address the reviews about small living spaces - it would really depend on your room choice. If you're picking a standard or deluxe room, youll find in this area almost all those room types will not even allow you to open a suitcase. I booked a suite to negate this space issue and was not disappointed. Moral of that recommendation is - you get what you pay for in the sense that, if you want a king room in the literal centre of union square, its going to be small. Outside of my room being well appointed, super warm (because SF was freezing when I went) and clean - I also was gifted a bottle of wine and chocolates on arrival. The Staff blew me away with how they operate and what they did for their guests. Big mention to Ann and Joshua for making my stay what it was... amazing. Give this hotel a chance, but understand - city living in SF means less space but bigger price, not just this hotel but anywhere. Thank you to the entire team for exceeding every expectation!

    Great boutique hotel in Union Square

    Great hotel in Union Square that is close to great shopping areas of San Francisco. The afternoon wine and cheese is a nice touch and the American continental breakfast has something for most tastes to get your day started. Would recommend and would stay again. The staff were all very helpful and kind.

    Great location and very comfortable

    Delightful place to stay - stylish and comfortable while surprisingly spacious. Very personable staff - great dinner suggestion of Italian restaurant. Lovely idea having drinks for happy hour. Nice way to meet other travelers. Only downside for us was the breakfast which was not our style. We prefer whole foods, less sugary, carb heavy options. Fruit salad was appreciated. Would definitely recommend staying there.

    Great stay at the Inn At Union Square

    This hotel is adorable! My daughter and I had a shopping weekend and stayed at this hotel which is just 1/2 a block away from Union Square. The lobby was clean, the bed comfortable and nice fluffy towels. This was also a very quiet room. We had the best time and will stay here again in the Spring when we come back for our tour of Alcatraz. Thank you Inn at Union Square!
