Paul's place is very practical and functional. Given the whole check in process is automated, it was easy for me to arrive as and when it suited me.
The room itself was very clean and the bed was comfortable. Everything is well labelled and works just as expected. The room was also quite which made it easy to get a good night's sleep.
Breakfast and kitchen facilities were sufficient. Cereal and coffee provided, although no facilities for doing any serious cooking - however, this was as stated in the listing.
Location is good, it is 20 minutes walk from Golden State Park (or a 5 minute drive). That park is well worth checking out as it is huge!
All in all, I had a great time staying at Paul's. I'd recommend it to anyone who is looking for a simply pain free stay in San Francisco.
