The appartment is located in the very centre of the old city, Bairro Alto, with lots of restaurants and bars. It might be a bit noisy in the evenings and nights, but this did't disturb us.
We found the way from the airport very quickly, as Sofia had described it very well to us.
We did not meet Sofia in person, but her friend met us at the appartment, gave us the keys and answered all our questions.
We didn't use the kitchen, but there is all one needs in case you want to cook and eat at home.
