We stayed 6 nights at Frederico's place. He showed us around the place and made us feel very welcome. The place was as it had been describe and had everything we needed and we loved the outdoor area.
The location was perfect as it was a 5 minute walk to Copacabana and 15 minutes to Ipanema.
Frederico was also very quick to respond to messages. We had a problem with the internet and he arrived the following morning to help sort it out and later that day it was fixed.
I would recommend Frederico's place and would stay again.
