I stayed at Dalias for 4 weeks to take a Spanish language class and I greatly enjoyed my stay here. After 4 weeks the apartment felt like home.
The surrounding area (Condesa/Roma Norta) is very nice. There are a lot of restaurants, bars, cinemas, supermarkets but you are also only 10min away (by foot) from Parque Chapultepec. The subway station Insurgentes is close by and the train takes you to the center (Zocalo) within 15min.
The communication with Dalia has been excellent. She responded to questions within minutes. She also has prepared a little guide with things to know about the apartment and information about the area. I can totally recommend to stay here!
