We stayed at Rafael's house for 4 days. Rafael's apartment is located in a nice street, full of portuguese calçada and trees. The house is comfortable, it was very clean (important point), and is well located (less than 5 min to two main metro lines that take you right to the heart of the city in 20 min). It has supermarkets near, and there are plenty of coffee shops and restaurants too. We decided to stay out of the center touristic areas as we knew that buildings are not always the best out there, and we did not regret the decision. I would stay again. Obrigado Rafael.
