My girlfriend and I spent 14 days here while visiting family in Rio and ended up spending quite a bit of time in the apartment given the stay-at-home advisories from authorities during the COVID-19 crisis. It surprised us to the upside.
The pros are many: the apartment is spacious and pleasant. There are three bedrooms, two of which have A/Cs, three bathrooms, one large living room and a fairly big kitchen. The couch in the living room and the bed we slept in were both comfortable, the kitchen had every sort of utensil you could hope for (even a cheese grater!), and we were located in a fairly convenient area. Finally, our hosts were extremely attentive. Eduardo, who managed our stay, was easy to reach, reliable, and very flexible on multiple accounts, including with check-in and check-out times. Moreover, when we told him that we had accidentally shattered a coffee kettle he was very understanding and charged us an extremely fair replacement cost.
The hiccups during our stay were not many, especially considering that we were there for two weeks. Of note: the apartment was a bit less clean when we arrived than we would have expected; the wi-fi's range is rather tight - only working well in the living room and one of the bedrooms; and the master bedroom's A/C is quite weak. Nevertheless, these were small inconveniences, and did not in any meaningful way detract from our stay. I would fully recommend others to stay here.
