Ray is a great host, and his flat is a terrific place to spend time in San Francisco! It is very cozy, in great shape, and has everything you need (including a Nespresso machine 😀). Then add the location to the mix, and you have the best place to stay in the City. Nob Hill is a great location to get to so many different neighborhoods by foot. I recommend staying at Ray's place if it's available when you visit San Francisco.
Thank you again Ray for being helpful and ensuring we had a memorable visit!
