All of the staff we encountered were very friendly and informative. Rooms were clean. Only problem was room was a little stuffy could use a better a/c unit luckily I had brought a small fan for us which helped us stay cooler.

Great budget friendly hotel. Travelled with my spouse for a long weekend getaway. Hotel was nice, staff were polite. Continental breakfast is offered but not much variety. Other than that I would definitely recommend this hotel. I would stay again if ever in the Bay Area.

Amazing place to stay in San Fran! In the center of everything and there’s public transportation super close by. The rooms were so comfortable and very quiet despite being downtown. We were even surprised with a room upgrade!

Reasonably good value - you get what you pay for and hotels in California are expensive. A small hotel with just 30 rooms and no other services. The room was clean and comfortable. Breakfast was a simple serve yourself. The location was excellent - lots of bars and restaurants nearby, Chinatown and Fisherman's wharf within walking distance.

Todo estuvo más que excelente en nuestra estancia, nuestras felicitaciones al personal! Agradecemos el upgrade de habitación que nos otorgó el hotel (sin estar obligados a hacerlo), debido a mi nivel en Expedia. La ubicación, inmejorable; a unos metros de Union Square y muy cerca de los principales puntos de interés de la ciudad. Con toda seguridad, volveremos a hospedarnos con ustedes en nuestra próxima visita a San Francisco!

Excellent location, excellent hotel. It's older but charming. I stayed here for a work trip by myself and felt safe. The breakfast was just ok, but good enough to get your day started. I was able to leave my luggage for a few hours on check out day so I could explore the city before my flight. I had an issue with the TV (which is also older, probably the only thing I didn't like about the room) but they fixed it right away. I would definitely stay here again. The location is steps away from everything - Union Square, cable cars, Nintendo store.

Nice breakfast and room was very nice. The elevator and some other things are worn. It's an old hotel, after all. But a good value.
