We have stayed with Cathryn for a period of two weeks, during our relocation to US. The location is on top of a mid sized hill with great access/convenience. The views during sunset are amazing. you need to walk a few ft to have a glimpse of SF FiDi/downtown and that view is kickass too. There are pretty good restaurants (you should try Plow and Papito) and shops within walking distance. Cathryn has all these details documented and ready for you even before you arrive!
The property in itself is amazing! You get a decent sized room for yourself and common area that you share with Cathryn. There is a patio that you can enjoy the sunset on (ofc its windy, but the views are mesmerising).
She knows the locality, the city, the state and sometimes the country too - in and out. She always had amazing tips, recommendations, tidbits, trivia handy and guided us throughout.
My wife and me - both are in love with the Kitchen (I have not seen a kitchen as well equipped as that) and the overall set up of the house. Everything is where it needs to be and perfectly organised! There is a private restroom that is reserved only for the guests just outside the room. No issues with the wifi too.
I would definitely go back to Cathryn's nest!
