Very well located, close to Union square and T/bart, restaurants, car rental or bike rental..Very nice staff, complementary breakfast and happy hours made our stay smooth and comfortable. It was a quiet week, and so a quiet room at night. Will come back.

Beautiful boutique hotel. Very clean, great bed and house keeping service. Great location, close to bart, cable car and local transportation. We felt very safe!

My stay was fantastic. The only negative thing I experienced was that they removed the US flag from its place of honor at the peak of their hotel in order to fly a pride flag in its place. As a veteran whos friends gave their lives for the US and whos coffins were draped with that flag, this was intolerable. There were plenty other places they could and did fly the pride flag. It should never fly in lieu of the Stars and Stripes.

I have stayed here numerous times. Each time has been outstanding and this time was no exception. Every area of my stay was top-notch but I want to single out the staff. Every stay, they have been amazing. They are so kind, considerate and welcoming. They have been consistently awesome and I appreciate it every time.

The emblem is a true gem. the staff from the moment we walked in until the moment we left were exceptional, friendly and accommodating. The room was very comfortable, and we loved all of the creative touches if you are looking for comfort, fun and inspiration stay here.

A Sublime Experience at Hotel Nikko San Francisco Our stay at Hotel Nikko in San Francisco was nothing short of extraordinary. From the moment we arrived, we were enveloped in a sense of calm and luxury that made this trip unforgettable. Hotel Nikko seamlessly combines understated elegance with the vibrant energy of the city, making it the perfect choice for both relaxation and exploration. The service throughout our stay was impeccable. Every staff member we encountered—from the front desk to...

Super cute inn right in the heart of San Francisco. The staff was so kind and made our stay enjoyable. Wine and cheese from 5-7 was such a great bonus to the already awesome stay. I highly recommend booking here! I will be staying at the White Swann next time I visit the city❤️

Host Alexis went above and beyond to assist us with our stay. She was awesome!

This was a great place to stay for our short trip to San Fran! The parking was super convenient and the staff were great!

The reception staff are friendly and welcoming, especially Sukina and the entire staff, the level of cleanliness is excellent and everything is excellent

Very nice hotel in a good location.

Great staff, great property

Great!

We stayed with our preteen and little guy and it was wonderful. Area felt pretty safe. We had a bay view room and got to watch the lighthouse at Alcatraz at night. Real close to dining, Ghirardelli Square, Fisherman's Wharf and just a couple blocks from the Big Bus station. Breakfasts were good and definitely saved money not paying for that every day! They are strict about the breakfast cutoff.

Castle Inn was safe, clean and economical. Our only complaint was a wet towel was left on the back of the bathroom door. Other than that the room was very clean, it was safe and had free parking.

Wonderful hotel in the middle of the city!! Fast access to china town. The beds were super comfortable and the staff was exceptional.

Always a pleasure staying here! Lovely staff and beautiful hotel!

Great area! Convenient on foot, public transportation or if you opt for the Big Bus. The lounge, starlite, upstairs is swanky, but if you are alone expect the bar, they will not allow you to utilize a sofa for sunset. The cocktails were fantastic, bartenders eager to please; but typical of San Fran, pricey! The Post had hands down the best lamb shank I’ve EVER had with an astounding summer version like a succotash of summer vegetables! The oysters were light and incredibly FRESH- and quite...

The staff was amazing and very helpful as this was our first time in San Francisco. There are many restaurants and shops within walking distance. We were conveniently only 1 block away from the cable car pick up stop which takes you all the way to Fishermans Warf.

All of the staff were friendly and upbeat. The front desk personnel were very helpful
