The place is located between the subway stations of Embajadores and Acacias; good position if you choose to take the trains, although I suggest a nice walk to fully experience the city (especially as an alternative to metro 5).
The apartment is not very large but fully reflects the website's pictures and is located in a quiet and peaceful condominium. The hospitality of Javier is to be rewarded: he welcomed me with water, maps and advice on where to eat (a barrio for every need) and what to visit.
