Alex's loft is even cooler than advertised, a quiet rooftop getaway above the beautiful, leafy Roma Norte neighborhood, about a half-hour walk to the historic center of Mexico City. The bed was comfortable; there was plenty of hot water in the shower and the roof terrace was spacious and filled with plants. It did get unseasonably cold outside at night when I was there, and this eco-friendly flat doesn't have a heater. An extra blanket did the trick for me, but other guests might want to pack accordingly.
I didn't get to meet Alex in person but his lovely associates went out of their way to make me feel at home and to address any problems I had. Great place.
