Sung is a great host. I live near by and rented his house for my family's visit.
Everything is meticulously organized and planned to accommodate a family. (i.e. crayola and pool noodle) We felt like home. Sung often sent me messages during my stay to check if everything's okay.
Not to mention that it is a beautiful neighborhood with nice people. If you are visiting Bay Area this is a great location to relax peacefully at the end of the day.
