Gonzola and Sandra were very very friendly and proactive since I did the booking. They would occasionally send me recommendations of restaurants/ places to explore. Also Angela, the person in charge of checkin and check out, was always there for us for anything. We had some problem with the boiler and she had it fixed very quickly. The apartment is very safe and has a lot of facilities in it (such as nice receptions, pool, gym, etc). Mexico city was vibrant and lively, but we were a bit concerned about safety. The area around the apartment was very crowded, but felt very safe. It was a great experience.
