My friend and I couldn't have had a better stay in Mexico City. The apartment is gorgeous, full of light with beautiful mid-century decor (and great books on the shelves), set off a lovely plaza on a quiet block of hip Roma Norte. Rafael and Margarita were warm and welcoming, very helpful with local tips, and even left us a little bottle of mezcal (which happened to be the best one we tasted on our trip - we both bought a larger bottle of the same brand to bring home). I highly recommend that you stay here - and even, despite the lure of the neighborhood right outside your door, that you spend an hour or two reading in the bright living room, doors open to the plaza.
