My girlfriend and I had a great time in Rio, and we are really happy about our first booking through airbnb.com
The apartment is perfectly located just 200m from Ipanema beach and is also very close to the subway which is very convenient for getting around the city. Apart from a broken washing machine, the apartment was equipped with everything you'd expect from a modern home. Luckily, there was a dry-cleaning laundry just across the street, so that problem was solved easily. The Wi-Fi worked properly after some initial password trouble (don't use capital letters).
The entire building is guarded 24hrs which made us feel safe at all times.
As for food, I would strongly recommend a visit to the restaurant Zuka in Leblon. Best dining experience in years!
I would also like to point out that Andy was very helpful during our stay, and responded quickly to all our questions.
