I very much enjoyed staying at Silvia's place. She is a kind and friendly host who became a friend during my stay. I usually require a work desk, but in this case the one in the room was way too small, but it wasn't an issue as I was able to use the dining table. The internet is perfectly excellent. There are lots of nice restaurants, cafes and bars around the area.
I did have an issue with being mugged at Copacabana Beach but this isn't a reflection on the listing or the host in any way, more a reflection on me not being properly prepared or having done my research beforehand. Be aware that thieves target tourist areas, which Copacabana is, and don't walk around with nice watches or jewellery, or wallets full of cash (just carry with you the minimum that you need), and don't go down to the water at night.
