Gregg was very nice. He shared the kitchen and food to us, and there were maps and history book of SF in the room, which really helped us learn a lot about SF. The room was kind of small for two people, but the house was beautiful and well designed. In the garden, you could even see a view of downtown. Gregg was good at talking and we had a good time to talk with him. We both enjoyed a good time in his house :D
