Guillermo has been the best host I have ever had, outside of family. My traveling party consisted of two friends, my brother and I (Total 4). This was my (our) first time using Airbnb and it was an Amazing/Great experience, largely due to Guillermo being our host. Our trip didn't start as well as most do starting by the flight being delayed due to weather conditions. We did not arrive to the apartment until late at night, close to 1200 AM, almost 1.5 hours than initially expected. Guillermo was there at the lobby waiting to receive us and eased our worries/concerns about getting into the building, finding the apartment and all those worries when traveling to a new area and having so many first-time experiences. He showed us the apartment and everything that was at our disposal through the apartment complex and all its amenities. It was a fully stocked apartment with everything that you might need in order to facilitate your visit and enjoy it to its fullest. Dishes, spices, pots/pans, soap, shampoo, towels, hair dryer, coffee-maker, Clothes Iron, washing machine w/ detergents, internet, etc. Guillermo gave us tips/pointers on the things in our vicinity as well as provided us w/ menus and information pamphlets of things to do in the city. When I required some information regarding places to visit, how to get there, best way to get there, etc. etc. Guillermo always answered our questions in a timely and polite manner. I would most definitely guarantee this apartment when visiting Mexico City as well as Guillermo himself for any hosting that he provides. I (We) are more than pleased with our experience and are very certain/aware that it was in great part due to Guillermo. Muchas Gracias Guillermo! La experiencia fue excelente en gran parte por ti. Lo agradecemos mucho.
