I rent out my music room / library. The Room is on the second floor so you have to take a flight of stairs. The Rooms comes with TV and tons of music and books - and of course : free wifi.
Your own private bathroom is less than 5 feed from the guest room away.
Access to terrace with bay view and bbq. And in the Lounge is a bigger TV.
If needed we can recommend local restaurants and wineries in Sonoma and Napa, also shopping tipps and sightseeing information :-)
