I absolutely loved my time in Santa Teresa with Amala - she is a very lovely and helpful person with good vibes! No complaints whatsoever! I'd recommend her accomodation to someone who wants to stay in the "authentic Brazilian" part of Río - if urban beaches aren't your priority.
Amala's house is located within walking distance to the Selaron Stairs, Lapa, and the Gloria metro station. Santa Teresa in itself is one of my new favourite neighbourhoods in the world and Amala's house there is also located near a great little cafe that serves the famous cheese bread and açai!
