We had a great 1 month stay in Kewpies apartment! She is a great host, and the apartment is equipped with everything needed for a comfortable stay. The place is perfect for two people, and there is even an extra mattress for guests.
The neighborhood is great, and there are plenty of restaurants, supermarkets, padarias, pharmacies etc just outside the doorstep. Also, Flamengo metro station is just a 5 minute walk away. That means going to Centro, Copa, Ipanema, Leblon etc is super fast and easy.
We are definitely going to book here again next time we're in Rio :)
