There are a number of hotels around downtown San Francisco, ranging from old and outdated to newer and/or more recently renovated. The rooms at the Parc 55 are spacious and reasonably well appointed, though they are starting to show some age.
Overall, the value is average leaning toward a bit expensive, even by SF standards. That said, given the location and high quality of service, it evens out. The bar area is nice, and you never know who you might see (e.g., the nights I was there, a few players from the LA Angels were in-house). Expect to pay for the drinks, though.
The hotel is located very close to the Powell station (BART and Muni), has plenty of taxi and shuttle service, and is within striking distance of several attractions (including a reasonable walk to Chinatown, a couple blocks from Union Sq, less than a block off Market, etc.).
Pro tip: ask for a high floor for some great views of the city. I had a high floor room w a great view of SOMA and on out to the ballpark and Mission Bay.
