We stayed at Ming's place during Dreamforce'16 . With 30mins by Uber or 40mins by BART to the conference,this was one of the few affordable options that we had near the city.
The place itself was really spacious and very clean and even though the beds were not very comfortable, we did enjoy our stay.
Did not get a chance to meet Ming but he was very responsive over text if we needed anything ( wifi password, etc)
