We had a great stay at Federico's place. We were arriving later than expected, and he was very responsible to our messages and flexible with our check-in time which was greatly appreciated. The location was wonderful - lots of local places around to eat, or a walk or quick Uber to all of the hip restaurants and bars in Roma Norte and Condessa. The apartment was clean and had what we needed for our 5 night stay. Being that you're in Mexico City, I would suggest bringing ear plugs if you're staying on the weekend, as the street can be a bit noisy, but during the week it's very quiet. Also, as someone else noted the water pressure is lacking, but we made it work. It's a great value for the place and I highly recommend it for anyone visiting Mexico City!
