We had a great stay in Vitor's apartment, which main advantage was the fantastic location in Copacabana, just minutes walking distance from the beach and Metro station. Furthermore, the apartment is equipped with everything needed for cooking, from stove, oven and refrigerator to utensils necessary for preparing and serving food and drinks. We were provided with towels and we value the washing machine, which we used a lot. Air conditioning -essential in a city like Rio- while a bit noisy (as it is not split type), works good, rapidly cooling the apartment.
To us it did not matter much, but there is no TV in the apartment. On the other hand, internet via WiFi worked great.
The apartment is modest: there is no luxury there (the bathroom lacks a little bit of maintenance), but we are satisfied with the price-quality relationship since we found in our Airbnb research for accommodation places well below the level of Vitor's apartment (and worst located in the city) at a much higher price. My only suggestion to the host would be a renewal of the bedding, even when the quality of rest was good.
We did not meet personally, but Vitor sent his brother in law Marcos to give us the keys to the apartment, and also left two cold beers in the fridge to welcome us (which was great since we arrived from a long trip on a hot day ). Marcos was also friendly and had the patience to wait because it took us some extra minutes to find the address, not because the area being isolated or unsafe, but due to the impossible traffic happening the day of our arrival (31/12) since Reveillon Party preparatives. Later that night we could go and return by walking to that amazing fireworks show at the beach.
There is also a Doorman permanently present at the building's lobby to assist you as you arrive. At night it's very easy to find taxis and buses outside the building, and there are hotels and some business open 24 hours in the same street, and that's why we never felt unsecure even at night. Well, I fully recommend you to consider this apartment for your stay in Rio, as it is a great base to start exploring the beaches or downtown, or the many attractions the Cidade Maravilhosa has to offer, and also because the host will be accesible to address the concerns you may have.
