Guillermo was great with us. He kept our luggage at his own place before our check in and after the check out. Communication with him was perfect and he was always prompt to help with anything we needed in the apartment and in the city. He helped me getting a card for phone and gave me many valuable hints in how to move around and places to visit. Guillermo is fluent in English and this helped a lot our communication face to face.
The apartment is small but not tiny it is in the top floor of a busy area. During the day is noisy like all places in Mexico city but at night gets quiet enough to sleep. The shower like some people said isn't great because doesn't have much pressure. I noticed that most places in Mexico have the same issue and I don't think that Guillermo can really fix it
The location of the apartment is very good. It is not close to the centre so you have to take the transport to move around but it is only 4 blocks from metro line 2 . You can go to many places just using this line. In front of the metro station there is a Walmart and Starbucks making very easy to get and carry groceries. As a bonus there is a veggies/fruits street mercado just crossing the street from the building. My daughter and I were delighted with that. I certainly would stay again at this place if back in Mexico city.
