Kawika is a great host. We found everything we needed and even more (thank you, Kawika, for the wine and nice Hawaii sweets!)
A very calm and safe residential area.
This is South San Francisco, be ready that the city is a bit far (20 min drive, 25$ with Uber, the train transportation is not that convenient) but it is a good solution for those like us who has to cut expenses.
If you plan to spend hours in the flat it can be a bit small for 4 persons. But we came to explore San Fran from early morning till late evening and it was good for us.
