Guillermo was a great host. He had the apartment ready for us and it was no hassle getting the key and settling in. The guards were very friendly and helpful and the area among the best in all of Mexico City, safety was never a concern. Guillermo provided details on everything we needed to know and even left us a few surprises in the apartment that made our night. I give Guillermo the highest mark in quality and definitely recommend staying in his apartment and experiencing the beauty of Mexico City.
