Roy Mil Gracias!
Thanks so much for the wonderful hospitality, my mom and I had the most fun and amazing time while staying at your beautiful apartment. We enjoyed the heart of Mexico City thanks to the convenient location of your place. My mom just turned 70 and we were able to walk everywhere; every day we were able to find treasured-new places to visit in the neighborhood ( a coffee shop with a museum, Santo Domingo church, wrestling arena, live-music, delicious traditional-food made from scratch, best lime-roasted elotes... etc...)
Planning to comeback and stay at your place very soon :)
