This is a perfectly situated unit for exploring the Roma and condesa areas of Mexico city. It gets very hot in the upstairs portion of the unit even with the air conditioning running when the temperature outside gets above 70. with the sun being in the South it hits the three-story windows as soon as the sun rises. I'm not sure what it would be like in the summer when the sun is in a more northerly trajectory. Installing some blackout shades would be very helpful. The first floor bedroom was far more comfortable as regards the temperature issue. One other problem was a neighbor who has an annoying barking dog that seems to start barking every night around 10:00. It takes them a good 15 to 20 minutes before they step outside and actually address the problem. Powers that be in that neighborhood should find the owner and get him to address his noisy dog!
