The good: One of best locations in Ipanema. Meters from many markets and restaurants, a block from what I think of as the center of Ipanema. Great TV with fast internet, premium channels like Netflix, HBO, Disney. Functional kitchen. Very good and quiet air conditioning.
The bad: Lots of noise. Thin walls, ceiling and windows. You can hear neighbors playing music, etc, you can hear upstairs neighbor walking in hard heel shoes or hurrying around without shoes, hallway is a sound chamber as barking dogs from other end of building sound like they are outside your door. Windows let in way too much street noise. If you are a light sleeper, you need ear plugs. Unless you love a noisy environment then this is probably not the place for you.
