Old hotel but completely remodel. Carpet and beds extremely clean, walls panted and modern shower and bathroom. Very convenient location, close to all main downtown attractions, cable car and bus stops. Area seemed safe enough (it’s still downtown SF). I’m 4 stars because the rooms and bathrooms are really really small. The bathroom sink was in the room itself, to say how small was the bathroom. It was not a problem for us as we were out most of the day, but if you have 2+ people with different habits, get ready to have not much personal space and privacy. Overall a good experience!

It was just OK. But it was balanced with what we payed. Don’t understand the “resort fee” in this hotel, it is obvious in Resorts but not in this type of properties.

Place was nice, though the room did have a faint mildew smell. $37 resort fee is absurd and totally not worth it. Worse was that Expedia didn’t disclose the resort fee when I booked (it did for another hotel nearby that I passed on)… I would have chosen a different hotel. Disappointed by both Expedia and the hotel for that.

Room was clean and comfortable. We were there in January and the heat worked great. Breakfast wasn't much and we decided to eat at the French bistro next door, but only because we wanted to spoil ourselves. Parking in the nearby garage was $48 for 24 hours. Probably the going rate in a big city like San Francisco.

I had such a great one-night staycation at the Hotel Triton with my dog Tigger! I had to be in town early the next morning and I'd always wanted to stay here, and I got an awesome rate here on Expedia. The room was nice and the bed was super comfortable. Pets stay free and Tigger even got her own food and water bowls in the room! Great location right near Chinatown and Union Square, and the lobby is retro and cool. I love the history of rock & roll bands staying here over the years. Shout out to front deskers Alice, Esmeralda and Jay for their great hospitality! Highly recommended!
The cool retro lobby.

Oops, she only went on the bed for the photo. She slept on the floor!
