My friend and I stayed at Igor's apartment for 4 nights. Our stay was amazing, I couldn't ask for more. Igor was very helpful and accommodating, he allowed us to arrive a bit early and to leave late, he gave us useful tip about the area and Rio de Janeiro in general and he even gave us his membership number to get a discount at the supermarket downstairs.
The apartment itself is beautiful and very modern with all the amenities you need - fully equipped kitchen, AC in both rooms and in the living room (very important in the hot and humid climate of Rio), a washer, a gas water heating system (not common in Brazil, much better than the electric water heater they usually have above the showers), flat screen TV and a home theater with bluetooth.
The location is perfect, right between Copacabana and Ipanema, offering you the best of both neighbourhoods. It's less than a 5 minute walk to Copacabana beach and to General Osorio metro station (Ipanema beach is within a short walk too).
In my opinion it's the perfect location for tourists in Rio.
I would definitely stay at Igor's apartment again and I highly recommend for to 2 people or more. It's not the cheapest apartment you could find but if it's within your budget you should book it.
Thank you for everything Igor!
