I was in São Paulo to be interviewed for an University job. My intentions was to stay in the apartment studying and preparing my talk. However, silence is not an option. Doors and walls are thin. I could hear the elevator's doors opening, the snore of other guests, and the cleaning personel all from inside my apartment. Cleaning starts at 9 am and I could hear them talking and laughing.
On the bright side, you'll be hosted in one of the best neighborhoods of São Paulo, with food and drinks available 24-7, close to metro stations and with plenty of bars and restaurants around you.
