I was already the second time. Its perfectly located, close to the metro and the beach - with an amazing view from the window.
There are a lot of nice details, from the colorful walls until the historic books about the city of Rio de Janeiro. The apartment is very cozy and clean. Communication was always very easy. I would return anytime. Actually I even asked them to buy the place.... but they know, why they wont sell it: It's too beautiful.
