You don't know what will happen in Mexico City, and having a host like Veronica could be a life-saver!
My overnight flight arrived early in the morning, and she did everything she could do to check me in earlier. Also, I was unfortunate as the day I checked-in, the water supply in the building was cut off (which is not her fault at all, and it was the very first time for the building as well), but she promptly helped me out.
Going through this which could have been really frustrating for someone new in town after a long overnight flight, I could stay calm, as she always replied to me within minutes and tried hard to solve the problems with me. Veronica is super reliable, and she really takes care of her place and her guests.
