Great apartment. You cannot get any better when it comes to style and views in Rio de Janeiro. You can hear the sound of waves from the balcony. Thats how close you are from the ocean.
Location is great, however avoid going inwards on the close by main street. Go to Recreio and head north if you wanna go for a walk and of course if you are a tourist ask for tips from the Host since she is a local and know about every detail.
