Gonzalo & Sandra's flat is in a great location. It is 50m from the entrance of the block to the lovely, relaxed Alameda Park with the Belle Artes gallery and from there it is short walk to Zocalo the core of the historic centre. The flat is near a number of metro and metrobus stations, Hildago was particularly useful as it enabled us to reach Coyocan (Kahlo and Trotsky museums) and Audatorio (Anthropology museum) easily. There is a great choice of places to eat and drink locally and an excellent food market a couple of streets back from the park. The flat itself is a well equipped and comfortable and the complex has a range of facilities including a gym and swimming pool (you need a bathing cap but you can buy one in the Sport Dept at Sears, opp Belles Artes), a cafe/shop and a laundry/dry cleaners. We found Nancy the complex administrator helpful when we had a problem. However it would be helpful if there was an information pack in the flat, for example we did work out what to do with the rubbish but it was not obvious. While our communication with Gonzalo and Sandra was excellent, they replied quickly to emails, they have delegated the local management of the flat to an agent, Angela, and this did create some problems. We were unable to contact Angela directly by email and so had to use our UK mobile phone. The cell/mobile phone which should have been available for guests did not have a charger or credit. Angela did arrange our pick up at the airport and a driver for our visit to Teotihuacan but in both cases we were not that happy with the service we received so we organized our own transport to the airport on the final day. The Hilton Hotel, across the road from the flats, provides a reasonably priced limousine service to the airport (300 pesos) and luggage storage.
