Diogo, responded quite fast.
After he said that our first chose wasn't available , he proposed 2 more possibles which was indeed what we where searching.
So after a switch, which went very smooth, we arrived in the nice apartment in Leblon.
The apartment is at a good location on walking distance for different eating-places, bars, and off-cours the sea.
We only staid 2 nights but we loved the place.
