I live in Sao Paulo, Brazil and I work in the hospitality service.
Flavia and her friend (email hidden) right after we cot power and heat back after Sandy hit New York.
They were great guest, extremely respectful and clean.
Despite the difficulties of the NY downtown area (no subway, stores flooded etcetera) they were very understanding.
Flavia and her friend are great guests, and they are welcome back at any time!
