This location is great, it really can't be beat for the price. It has all the essentials, but it's not luxurious by any means. It's a good central place to stay for cheap.
It is an old building so it is noisy and you can hear everything because you're in the heart of Nob Hill, plus there are a ton of apartments in the building. Download a white noise app before bed and be prepared for some sub par sleep. Maybe bring some earplugs.
