Staying at Carina's house is a delight. This is the second time I have stayed with her, and everything was flawless, just like last time. The space itself is beautiful, with all of the amenities you could want. You can rent bikes (and helmets) from her. She leaves baked goods out if you need a quick snack. She is very responsive and thoughtful. I look forward to staying with her again next time I am in Palo Alto.
