I have been staying at Helen's for my business trips for years now. She is well located for appointments in Mexico City's three financial districts--not too far from Santa Fe, Polanco, or Reforma (Ángel de Independencia)). Lomas de Chapultepec is gorgeous, verdant, and walkable. Helen has off-street parking and an impeccable, very pleasant and comfortable home and garden. She is a very sweet and warm hostess who answers message rapidly.
