Sylvia's place is terrific. Great location, very clean, stocked with everything you need (maps, guides, movies, fiestaware, plenty of towels, hair dryer, iron, etc. etc. We ate out on the patio every morning, surrounded by plants. There's wireless internet. Cute dogs. Plus, the generosity of Sylvia. She's really a lovely, lovely person and gave us tons of ideas for good, cheap eats(Manuels' happy hour!), and was a general font of information. We rented bikes from her too, which was super convenient. All in all, a great stay.
p.s. her neighborhood is really neat, full of small bungalows, an gallery bookstore a block away, and a (closed temporarily) cafe located within a nursery a few blocks away.
