I'm in Oakland often for work. I always stay with Shimmy. Her place has become a home away from home for me. It's safe and comfortable and in walking distance to shops and restaurants and Lake Merritt, which is always a lovely spot for a morning run.
Shimmy herself is a super attentive and kind host. She really thinks of the little details to make your stay pleasant. She answers any questions right away and checks-in to make sure you're getting around ok.
