I had a great time at Carlos' place - though I only stayed for a couple of nights. Here's a quick rundown of the pros and cons:
Pros:
Close to central
Good internet and shower pressure
Great communication
Cons (I'm having to nitpick here!):
Shower temperature can finicky, shower nozzle cannot be directed
Another addition from Mexico to reddit's /r/TVtooHigh
Living room can be a bit dark, overhead lights too bright (no dimmer) for quiet TV watching
Overall, highly recommend this place. Carlos is super communicative, always responding within minutes even at 7am.
