I can't say enough about how Paco goes the extra mile to make sure your stay is good. This might be a bit long:-).
First, the apartment: we were a couple and another person, so the two bedroom two bath apartment worked really well for us. It was very well equipped with amenities, including being stocked with food (bread, coffee, ham, eggs, sweet snacks), kitchen ware, and toiletries. It was immaculate and stylist. Be aware that it is on the 4th floor, which actually helps with the traffic noise, but you do have to walk up. We don't mind but it might be a problem for people with mobility problems. Luckily there were fans for the bedrooms, as it was as warm as it ever gets in Mexico City.
Then, Paco himself: perfectly punctual, energetic, and there in a flash if you needed him. The extra: he provided us with a mobile hotspot to carry. And the big extra: Ecobici cards! More than that: one of our cards didn't work and he hustled to meet us at a restaurant, took our cards to the office, recharged them, and brought them back to us. Talk about going the extra mile!
I don't know if he speaks English as all of our communication was in Spanish, so I can't comment on that. But what a lovely person and dedicated host!
