Vanick's studio is a stylish basement unit perfect for a short-term stay. The space is cozy and nicely decorated, and it even has central heating which is rare in SF! The kitchen area is a little small for those that prefer to cook, but I never planned to cook anyway so it wasn't an issue for me.
The surrounding neighborhood is quiet, clean, and beautiful, and Vanick's welcome book has several recommendations for dining and nearby activities.
