Easy self check-in process and responsive hosts have made my last minute booking possible. While being a tiny home, it is well-designed and has everything you may possibly need (except maybe a washer) proactively prepped for your stay -- even minor details such as a USB charging cable and cold bottled water were taken care of. I've walked to San Diego Zoo that shares the park with a bunch of Museums, and you can use a bus to get to downtown and the waterfront. Buses cost a few dollars in cash, or download Pronto San Diego metro mobile app (also works with light rail trolley).
