I stayed 12 days in Rio for business and vacation. I met Duda upon arrival and he was very friendly, receptive and professional. He speaks excellent American English and understands American culture (I think he attended a small Midwestern college for 3 years). I had a minor TV problem ( my error), but when I got in touch with him, he responded promptly and was extremely helpful.

Pros:
Clean, organized apartment. Perfect for 1-2 people.
Nice bathroom w/ large shower. Has Washer/Dryer combo. Close to Beach. Close to subway (Metro) station ~4 blocks. Very close to 3 grocery stores (loved Hortifruti). I felt safe in this neighborhood but your comfort level may be different.

Cons:
Very far from Ipanema, Copacabana, Centro (hint: learn to use the Metro system...cheap, safe and easy to use). Few speak English in this neighborhood. Need more English language cable TV stations.

The apartment offers a good value and is recommended.
