Daniela is a great host, very responsive and easy to communicate with. She gave me very good recommendations of places to eat in La Condesa and was always ready to help.
The apartment is big enough for a couple but not for a long stay I would say, it has everything you need, a good bed, a kitchen, a balcony, etc.
The location is the best advantage of this apartment, it is in the heart of La Condesa, close to all the nice places in the area and it is a very good place to explore the rest of the city.
The only thing that I didn't like was that it was very cold at times, obviously in Mexico nobody has heating, so during my stay there was a cold front and the apartment was very cold sometimes.
