My mom and I had a great stay with Hao. The area south of his apartment (near the closest BART station) is a bit dodgy (which I expected, but others not used to urban areas might want to be wary), but the area around and north of his place is great. You're close to Market St and the MUNI running on it, which is convenient (though truth be told we used Uber a lot of the time). The apartment itself is exactly as pictured. The bed is comfy and the separate, private bathroom is great. Hao was super accommodating (he waited for us to arrive in the afternoon from SFO before going to work!) and in general was very nice. Thanks again!
