I booked Don & Kayko's suite for my parents who paid us a brief visit in SF. It was one of their first (perhaps their first) airbnb experiences and they loved it. The space was immaculately clean and as pretty as advertised. It's on a quiet and very conveniently located street in Cole Valley. My parents were mostly visiting us, but it would have been a great home base to explore the city's neighborhoods. Haight Ashbury and the Castro are convenient walks and there is a muni stop nearby.
My parents also appreciated the goodies that Don & Kayko left for them and their offer to pick up and clean any dirty dishes or cutlery. Communication was smooth and Don & Kayko were very proactive and accommodating when we needed to modify the original dates for the stay. I plan to have family stay here in the future whenever my own place is overflowing.
