Kevin's house was great. The studio was perfect. Clean, comfortable and quiet. It has its own its own private entry so you don't feel like you might be bothering anyone. It's also located in my opinion one of the best neighborhoods in San Fransisco. It's a safe family neighborhood with parking that is easy to find. And just a few feet away from the house is a really cool stairway leading to a trailhead up to Mount Davidson.
I highly recommend Kevin's studio for anyone wanting a great stepping off point to explore San Fransisco.
