We had an amazing time staying at Ruben's loft for the week. It's a really incredible space and in a great location in La Condesa. We walked pretty much everywhere most of the week and the neighborhood is incredible, right near great restaurants, several parks, etc.
The porch is a great place to hang out with amazing views and we really liked the building set up -- the elevator takes you directly to your designated apartment (super convenient). Ruben and Ricardo were both incredibly responsive to any question or request that we had. This was one of the best AirBnB experiences we've ever had and the next time we're in Mexico City we're planning on checking out Ruben's place first.
