As Gnilane wasn't in Mexico, it was her neighbor Pablo that welcomed me very nicely. He and his wife gave me all the advices to feel comfortable and proposed me a list of touristic attractions and were always available to give me advices.
The neighborhood is nice and safe and has a perfect position and good access to public transports (5 min walking to metro). There are plenty of restaurants of different categories (meal, price and service).
The room is comfortable and clean and perfect for one traveller. Even if I didn't have access to the kitchen (her appartement is totally separated and was rented to an other couple), I still had an electric heater to prepare myself my morning coffee. As it was very easy to find restaurants or shops in the surroundings, I didn't miss the kitchen.
Even if she wasn't there, Gnilane was always willing to help and wanted to assure herself of my wellbeing.
I recommend this place for every one, who wants to spend time in Mexico City without having to trouble for safety and wants a good location.
