I stayed at Marcos apartment for 3 nights. It was exactly how he described. The neighborhood was very very safe. I didn't feel in danger at any time, even walking back at 2am. very safe building with 24 hour security. I didn't get the chance to meet Marco, but he was only a text message away. I texted him alot with questions and he helped me out tremendously with suggestions of places to go, things to do, car service to/from airport, etc (his driver is great). He responded back to me immediately and seemed happy to help, never getting annoyed. The apartment was very clean and spacious. Exactly like pictures. All amenities for cooking, washing clothes, fast WIFI, etc are available. Mexico city gets chilly at night and at times the apartment did too. We didnt have control of the heat in the apartment. There was 1 portable heater available and Marco offered to bring more blankets if needed. It wasn't a big deal, but would have been nice to have control over the heat. Mexico city is wonderful and i will be coming back and definitely staying at Marcos apartment. I give it 5 stars and highly recommend it to anyone visiting. Very professional, top notch.
