Fabiana's place is superb, in a vibrant neighboorhood, but quiet street. Her recommandations for food and places are amazing! (Go for Rosetta restaurant and Panaderia!!!!)
We coffee crawled and walk in La Roma, Centro historico and Condesa and if you are willing to discover by foot, I would say that a lot is wakable from her appartment. Its central and charming!
Its also clean and has everything you need! Plus Fabiana is a great host! Dont hesitate!
