I've spent one of my first weeks of relocation to SFO at Han Chyi & Choon Hong's apartment and they simply made such a process totally hassle free. The apartment was carefully cleaned and accommodation is beyond any expectations: I was surprised by the amount of space and useful, thoughtful and young design. The neighborhood is safe and very silent, nevertheless it takes only 2 minutes walking to enjoy a good wine in one of the bars at Haights street. Best place I've rented through Airbnb!
