Great place, very clean and comfortable. It's in a nice quiet neighbourhood, about 10 minutes walk from Viveros metro on one side and Altavista metrobus on the other; 20-25 minutes walk from the centre of Coyoacan (nice walk along Av Francisco Sosa one block to the south). Host Liliana is a lovely lady.. she doesn't speak English and unfortunately I don't speak Spanish, but her son Paco (who lives elsewhere) answered all my messages and came over to welcome me and translate for us when I arrived. Recommended!
