Lourdes and Steve are fantastic hosts. Very friendly and helpful with great local knowledge. The apartment has lots of character - it's not too big but was perfect for our needs (it's actually bigger than the listings photos make it look). It's also in a good location being just a short walk, mainly through pretty streets, to the livelier parts of Coyoacan.
Apartment was clean and had everything we needed. No complaints at all - it was a great place to stay.
