Sofia's house is beautiful, spacious, well equipped. modern and comfortable. If you run out of art gallery time just look around you instead. Coyoacan is a large area and - along with neighbouring San Angel - the most attractive we felt. Take time to explore off the beaten track here, it'll be most rewarding. The city metro system is great but doesn't cover all areas but in the case of Sofia's house there are two metro stations within a twenty minute walk. I would thoroughly recommend staying at Sofia's place.
