My stay with Leti and Richard was brief but nice. They are warm and helpful, and always looking to make your stay easier and better. Their appartment has all you could ask for, nice view, nice and safe neighborhood, chargers and cables for your cellphone in case you forgot it (I didn't but still found it great), guides and maps to move trough Mexico City, they even have a metro card for you to borrow in case you may need it. Richard's coffee is the best way to start in the morning and he makes grear sandwiches too. They will ever be my first option every time I go to Mexico City.
