I've been to San Francisco a couple of times and they have all been different experiences.
I went by myself once in college and stayed in a hostel where I met people from around the world and went to different pubs.
The second time I went with my boyfriend and it was very relaxing and beautiful. We rented some bikes in Haight Ashbury and biked around the park.
This time around I brought my boyfriend and two friends. I wanted to show the joy and and beautiful places the bay has to offer. Although our flight got delayed 3 times and canceled once, we managed to get most of the things off our to do list.
Here are a few recommendations.
Hi San Fran City Center Hostel- I will always stay here for my visits in San Fran. They have great accommodation with great prices and an amazing staff. The hostel decor is just beautiful. Don't expect it to be a hotel because it is not, but I love stying here because of the people you come across who are traveling.
Bourbon and Branch- if you want to experience a true speakeasy. You will need to make a reservation in advance and when you arrive, you will see nothing but an abandoned place and you will have to figure out how to get in.
North Beach- there are a bunch of bars here so it's a great nightlife. Vesuvio cafe has always been a favorite of mine. It started in the "Kerouac et al. amid Beat-era".
Castro- Just start walking and if you hear music just go in. I went here after a couple drinks and started bar/club hopping. I felt like dancing. I met great people with great vibes.
Don't forget The Citylights Bookstore, Golden Gate Bridge, Fishermans Wharf and all those great touristy places.
Here are some photos for your pleasure.
