We had a wonderful time staying at Ryan's house in Cole Valley for a month. The pictures don't do it justice as the scale and ceiling height of each room is immense.
Ryan was always helpful and quick to address any minor issues. The area is lovely and gives you a true experience of life in the pretty Victorian homes and areas of central SF. Access to the Golden Gate park, Haight, Mission, Castro and even Hayes Valley areas is possible by foot or quick taxi. Cole Valley itself is a little gem of a village. So close to Haight but very different, with great bars and restaurants plus a number of useful shops for locals. The metro line passing through it makes it all the more perfect. I'm not sure I would want to stay anywhere else.
The deck at the back of the home is large and very pretty, surrounded by a canopy of trees and some amazing succulent plants. Most mornings the sun fills it and streams into the kitchen which gets heated beautifully even when outside might be a bit cold.
Since we stayed a month we loved using the big screen TV and catching up on a few box sets via Netflix etc. In the evenings the sun streams into the front reception room and you can watch it set over the skyline - which even provides a glimpse of the top of the Golden Gate Bridge.
In the interests of balance the only thing we can mention that wasn't quite perfect was the beds - not quite as comfy as we'd like, especially in the small bedroom which has a foldout metal bed and thin mattress. Nothing else was more than a minor quirk though, so we highly recommend Ryan's home.
