This is an awesome, unique place. Plenty of space and instruments around - we loved the electronic drum kit - and the bed was super comfortable. The patio is spectacular. Big back deck looking over (what I'd call) the Berkeley hills . The deck is about 40 feet above ground - the height of the tree tops, with lots of birds swooping around. At night, it's dark in the neighborhood so the stars come out, and we watched the crescent moon rise. We loved staying for a night - would have liked to stay longer!
Some people mention the parking. We found a spot right away both times we parked. These are narrow windy roads up here. Just drive slowly - it will be fine! A bit higher up the hillside there are parks, hiking, and some great views of the bay.
