We loved staying at Caroline's apartment. This was our home for 2 months while we were settling in Rio and it was just perfect.
Whether it be for a short time stay (or longer) the flat is ideally located.
Just a block away from the beach with all amenities at your doorstep. Restaurants, shops, grocery store, pharmacy, bank... EVERYTHING is within walking distance.
The flat itself is very enjoyable and well equipped and the terrace was my favorite place for breakfast with a view of Pedra da Gavea and chirping birds.
Although in a very busy area of Barra, the flat is really very quiet and the trees are so high that you would never think yourself in town.
I highly recommend this place to anyone who wants to stay in Barra da Tijuca while in Rio.
