Although we didn't have the pleasure of meeting Bianca personally, we did find that she is a gracious host and very responsive to emails and questions. Polanquito is a great area, near Parque Lincoln, Bosque Chapultepec and all the nightlife and shopping of a world class city. The flat was perfect for two couples (or three) and we loved the openness of the flat. You are close to most everything and safe. The street below gets lively at night so just know that the front bedroom will get some of that noise, while the back two bedrooms remain very quiet.
