My german co-worker and I spent 17 fabulous days at the apartment. We were at Rio for work proposes and we needed a quite, but very central place and we found it at Marcio and Joelma's place. There are restaurants, supermarkts, shopping center and pharmacies all around the building. Buses and metro right there as well. We were very well located and within 10 min of Copacabana beach by metro.
The hosts and the 24h security guards were amazing with us. There was a small complication with my room's window one night and they fixed it right away. Due to our working schedule we couldn't meet with Marcio and Joelma, but they were always lovely with us and we were truly happy with the apartment. We definitely recommend!
