Nice and friendly staff but rooms need to be refreshed, and continental breakfast is definitely not the best we ever tried.

A lovely boutique hotel. Older but authentic SF style. Room was comfortable and had a small sitting area with separate TV which was nice for coffee in the morning. The continental breakfast was quite good. Great location near Union Square - lots of shopping, food options within walking distance.

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.
