We had a great time at Alex & Anastasia's apartment in Rio. The apartment is just as it looks on the pictures. Small but with great optimization of space. You don't really feel it is that small. It is two blocks from the beach and very well-connected by bus, taxi (with a stop just one block away), and metro. We always felt safe around the area though it is not the nicest part of Copacabana in my opinion (the apartment is located very near Leme), I think the closest to Ipanema the better (though I guess prices might go up). Alex is a very nice host, he was waiting for us at the apartment to explain everything. He also showed us around the neighbourhood and gave us some good tips on supermarkets, restaurants, etc. He was very friendly and always answered e-mails very quickly. Wifi works very well. I would definitely recommend them as hosts and their apartment as well.
