Perfect location in Copacabana and a few minutes walking to Ipanema. Close to all the metro/bus/taxi stop to go everywhere easily.
The flat is very good for 2 persons, clean and convenient. 24 hours doorman, we never felt unsafe.
Dalia is a perfect host who showed us around when we arrived, explained a bit of the history of the neighborhood, showed us a few good spots to eat (best breakfast place across the street) and explained how public transportation works (very useful!). Not to mention the sweet food she had left in the kitchen for our arrival!
I definitely recommend her flat for a stay in Rio!
