We stayed in the apartment for two weeks, working as digital nomads this is a great place to rent; super fast internet, comfortable chairs, great location with loads of restaurants and landmarks to visit and a good gym nearby (Trindade Fitness Hut). The hosts Ana and João are very friendly and super responsive. Everything is brand new and clean, something we value very much. Also the TV system works with AirPlay which we liked very much, Netflix and other content apps are preinstalled. The kitchen is well equipped but we ate out a lot anyway.
The downside to this place is that the street is pretty loud and people are smoking underneath the balcony almost the whole day; workers from the restaurant and Uber Eats drivers. So opening up the windows was only an option early in the mornings. The airconditioning was working again, as another reviewer said it was broken before, but it's not really getting colder than 22 degrees in the place. The owners know about it and are working on it. Last thing is that you have to be aware that it has a (pretty stiff) queen size bed, around 140x200 cm I would guess. Too small and stiff for us, so I slept in the living room on the sofa bed. But that's personal taste, others have slept like a baby I read in other reviews.
Conclusion: price/quality is up to par and would recommend staying here if you're not put off about the few downsides :)
