I have stayed at Tereza's place for the month of January while visiting Rio.
First of all the place is amazing! - with amazing views, amazing light (it is a rooftop apartment so you have a great view) the location is very convenient and takes a 5 min walk to be on the Copacabana beach. The neighborhood is very lively (and safe!) and has everything you might need, from supermarkets to drugstores and restaurants.
Tereza was very well prepared, communicated fast and clear and exceeded my expectations.
One night I had lost the house keys and when returning to the apartment (around 4AM) she was very quick to respond and offered and instant solution. This is absolutely great and goes beyond anything i have experienced while staying via Airbnb.
I can't recommend Tereza's place enough. Thank you!
