Sheila's apartment is in an excellent location! This was our first trip to Rio and staying in Copacabana, beside Cantagalo metro, made it very easy to navigate around Rio and we felt comfortable with the city almost immediately. It is also in a safe neighbourhood.
Sheila was a good host, welcoming and on hand for if we needed anything.
The apartment wasn't kitted out with modcons but we were too busy exploring Rio for it to matter, it suited us for what we needed: a safe place to sleep :)
