Standing proudly on San Francisco’s Union Square, this grand hotel has welcomed guests since 1904. Full of history and classic charm, the original landmark building is complemented by the Tower, where a glass lift (check it out at night when the city is all lit up) will take you to recharge in your room, complete with Heavenly Beds®. Back in the impressive lobby, enjoy the vintage vibes and spot the cable cars pass outside — experiencing San Francisco could hardly be easier. But before you do, why not grab a classic Italian coffee from Cafe Rito, or even a slice of pizza!

We came up from the South Bay with our kids for a 4th of July staycation, and this hotel is underated!
The location couldn’t be better—right across from Union Square, steps away from the cable car stop, and NEXT door to the new Nintendo store (which our kids were super excited about). Yeah, some stores in the area have closed, but a lot are still open, and it was way less crowded than it used to be, which was actually kind of nice. The streets were clean too. If you’re visiting from out of town and wish to walk, just ask which streets are best to stick to—hotel staff were super helpful. Valet parking is available for $80, but there is public parking under Union Square for $40 a night.
Everyone at the hotel was really friendly. We had a perfect view of Union Square. Beds were comfy, room was clean—no complaints at all.
If you’re thinking about staying here, don’t sleep on it! Check out Tratto and La Travesia nearby, the food was great!

A special shoutout to Jeff Squino at the concierge desk! Jeff was incredibly friendly, knowledgeable, and genuinely eager to help. Whether it was local recommendations or tips to make the most of our stay, he went above and beyond with a warm smile and professional charm.
The hotel itself is beautiful, combining classic elegance with modern comfort. From the grand lobby to the well-appointed rooms, everything was clean, stylish, and welcoming. I’d gladly stay here again and highly recommend it—especially thanks to amazing staff like Jeff who make the experience truly memorable.
