There couldn't be a super "superhost" than Ruben, which he should have. He is almost selfless in giving what ever he can, but knows when to step back. His background is from Couchsurfing, which explains why his motivations are different. He is an excellent communicator, and a native to Mexico City, who you might want to hire as a guide, even if you don't stay at his place. His apartment is central and airy. It is important to note the room is not on the street, so fairly quiet.
