I'm a 21 years old French female student doing an internship in NYC !
Adèle spent 3 months in my apartment with her boyfriend and they were respectful and gave the flat back really clean.
Everything went right and I will recommend them.
We hardly saw Adele and her boyfriend (!) but they seemed very friendly.
Adele and her friends were great. We hosted the four of them over the weekend of Obama's inauguration, and they could not have been more polite or respectful.
