Brian was great from the moment I booked the Apt. He provided a great list of recommendations, was very quick with responses to questions I had, and was a pleasure to deal with.
The apt itself was perfect for 2 couples. The back patio was very nice for getting fresh air. The kitchen was perfect for making some quick breakfast and getting out to see the city.
The neighborhood was great for people watching. A bunch of fun divey type bars are located just a couple blocks away on Valencia, check out Elbo Room, and Delirium (on 16th street, if you're into a really divey bar). Mexican places everywhere for late night munchies.
There are definitely some shady folks walking around, but you are in San Francisco, every 3rd person is homeless or crazy, gotta love it.
