If there is a future award for best host in all of Condesa and Roma I'm confident Lina would win it.
This is not just a way to make money for her: she clearly enjoys meeting and sharing with people staying at her place.
I've been AirBnBing for well over a decade and I don't think anyone's been as thoughtful and helpful. We spent lots of time talking, and I had to always remember to share useful information with her, otherwise she would just keep on helping and helping!
Traveling alone, if you don't know someone in a foreign country, has challenges. Lina was super available to give useful tips about the area, and because we did have things in common, chit-chatting with her was a pleasure. I spent almost 2 weeks in Roma and Condesa, and I really don't think you can be in a better neighborhood than hers.
