Location, location, location!
I think you couldn't find a better location in the whole city of Rio, in the heart of Ipanema and very close to the beach and the metro station.
The area and the building feel very safe. The apartment itself accommodates easily up to 6 persons. There are 2 rooms, one with 2, and another with 3 beds, and a really huge living room plus adjacent kitchen. The interior may not be the most modern, but functional and everything works. I can recommend this place!
