My flight from Mexico landed at sunset. Google Maps was wrong about my AirBnB host and the airport taxi dropped me off in the wrong place. Where the hell am I? It was getting dark and I didn’t know how bad this area would get in a late hour. I had a wallet full of cash, a backpack, a passport, and my phone. And nothing I wanted to lose in a random foreign city. I followed the street numbers south for four blocks until I found the host’s building. She welcomed me in and talked my ear off for an hour. She had a nice apartment with a comfortable air conditioned room and an excellent terrace. Just like that, Havana was my new favorite city.
