I am a 30-something Brazilian lawyer from Rio de janeiro. I don't smoke or drink and I always try my best to be a good guest. My biggest concerns and requirements are being on a safe neighborhood with easy access to the bus or Metro, wi-fi access, TV, a good bed and bath as well as access to a washer/dryer.
I travel alone and on business so I am not a noisy or messy person. Just let me know the rules and rest assured that everything will be fine.
