Thank you, Hugo, Margarita, and Corey for having me 2 weeks in your apartment. I haven't seen much of Hugo who doesn't live there but he always took care immediately (via AirBnB) whatever came up; e.g. there was a problem with the heating. He also gave me a lot of information about Harlem and whatever I might have asked for which I really appreciated. With his mother Margarita, I had long, nice, and interesting talks. And his brother Corey responded to everything I asked for. Everybody went well out of their way to make me comfortable. The location was very convenient for me as I needed to make research at Columbia which is a 25 minute walk. I felt always safe walking there alone. There are also buses and the 1 subway nearby. The accommodations themselves are simple but very clean.
