My house is very simple, is located in a city not very famous, but it's near from all good places. We have 2 TVs, a computer with internet, DVD, movies (if you want to watch), phone, and if you want something I get for you.
The neighborhood is very, very calm, so you can relax. My family is very normal, I think you wouldn't have any problem here. Whatever you want you can ask for the people that take care of the house, they live in the house behind mine.
My neighborhood is calm and quiet, short walk to the public transportation, everybody here is very kind. And 20 minutes by car from the biggest city in South America -- you have a lot of things to do like movies, theaters, malls, parks and a lot of great restaurants and nightclubs.
To the exchange, I'm thinking of going alone. I'm 18, very normal, single, non smoking, no pets, no children. I'm a student and an English teacher. I like art, beautiful places to visit and relax. And you can be sure that your house will be in great hands.
