Hotel Des Arts is a quaint small hotel near the Chinatown gate in downtown San Francisco. It's a great place to stay if most of your time is spent exploring the city and going about. Definitely not a luxury hotel, but the price should tell you that. Easy to check-in, kind service people, and relatively quiet. Great Irish bar next door!
There were a few issues that I could see affecting other guests. If you rent one of the themed rooms, the restroom is down the hall. Not an issue by itself, but the space for the shower and toilet is tiny. I would not recommend this listing if you are hefty or a bodybuilder. I had a mosquito in my room, which was painted primarily brown - very difficult to catch it, but it doesn't seem common. The bed might not support heavier people, creaked a little.
