It was a pleasure to stay at Marco's place. He owns a very beautiful and spacious apartment in one of the safest and best located neighborhoods of Mexico City. It is conveniently close to many means of tranportation (Subway, Metrobus and Turibus, as well as a taxi stand) and to some of the most important touristic sites. You can actually walk (ca. 20-25 min) to the Antropologia and Tumayo museums and to the Chapultepec Castle.
The apartment is exactly as shown in the pictures and is very clean. One person sleeps very comfortably in the bed (two would have to cuddle a little) and the bathroom is for your use only. Furniture and appliances are all new and you will have plenty of space for your luggage and clothes. Marco was kind enough to leave room in his fridge and shelves in the kitchen and even cooked me some quesadillas when I arrived in the evening.
Marco is a great host and a very kind person. He is absolutely polite and respected my privacy. He used to write me emails with usefull information and was very generous by taking me with his own car to visit the archeological site of Teotihuacán (thanks again for that!). The communication with him before and during my stay was absolutely fast and easy.
I would definetly stay at Marco's again and could only recommend his apartment for a nice rest and great chat!
