Lovely stay. We arrived in San Francisco and were met by David's property manager. We were able to check in slightly earlier than 3pm which was nice.
Pros:The studio itself is in a prime location in North Beach, many excellent restaurants in close proximity and walking distance from fishermans wharf, the city etc (obviously dependent on your fitness given the large hills!). The bed was extremely comfortable, shower works very well and kitchen adequate although we didn't really cook at home at all!
Cons: There is quite a loud noise that comes from (we think) the generator in the adjacent convenience store, I would recommend bringing ear plugs if like us you are not used to any noise at night!
