Letícia's place is great for a flight connection at MEX. It's located very close to a Metro station, and some buses ride nearby, and they also go to the airport.
The place is nice and cozy, perfect for a short stay. It can be noisy if you open the sliding door that takes you to the balcony, but it's a minor detail, but if you keep it closed you won't hear a thing.
I definitely recommend this place.
Letícia is also very nice.
