The location is good. There's a laundromat across the street and plenty of supermarkets nearby, plus it's a short walk to the beach.
The apartment is smaller than it looks in the pictures. The layout is weird, with one long narrow hallway leading to the main bedroom at the back. This is the only window you'll get. It's not sealed well and rattles with the wind, plus it's very noisy.
There's an unexpected 30 reais fee to use the aircon in the other windowless bedroom. Overall, the apartment is very stuffy.
Wifi and stove worked great.
The bathroom isn't great, with a sink inside the shower cabin (as well as brooms). The toilet doesn't flush well. The rule is "no paper in the toilet" (and you'll get fined, the first thing the host checked during the checkout inspection was whether the toilet flushed!).
Note that nothing is provided (i.e. no towels, etc.).
Not an awesome experience but fairly typical of Copa apartments
