We found the rooms clean, modern and just as presented in the ad. The location is very good and close for getting to places in the city, with the benefit of still being in a nice quiet neighborhood. We found suitable street parking every day as well so that was also as advertised. We stayed 4 nights and it worked well as we were out and about a lot.
For a longer stay I think we would have missed not having a sofa or armchair to sit on though, as the only option for sitting is the very small kitchen fold out table with small plastic chairs. One evening when we got back earlier and wanted to relax and read we really wanted something more comfortable, but as mentioned it is fine if you are busy and out and don't need it.
The kitchen is nice, modern and has most things you need and all in good working order. The only thing small inconvenience was that the only sharp knife was a large serrated bread knife, so when you want to carve meat or cut up tomato for a salad its difficult. Wifi worked well most of the time though was slower just a couple times.
All in all however I would certainly recommend it as a very good, clean place for short term trips in San Francisco.
