Only a few blocks from the beach and 3 min from the metro station.
I didn't feel unsafe on this area even late night(of couse, you need to take care).
Many restraunts, bars, supermakets around there. The apartment doesn't have a wash machine, but laundry with self wash machine is close.
Natericia was very kind and helpful. You can trust her.
I was happy to have stayed there!
(just a tip: If you need a tourist prepaid SIM, ONLY Claro at Shopping Leblon has one, 60 Real. Another Claro or TIM doesn't have)
