Our experience with Stefano's home was fantastic. Stefano and his wife were extremely easy to communicate with and were perfect hosts. They were always around to answer questions, offer tips, etc. They even helped connect us with a baby-sitter, who proved to make the stay even nicer.
They had two baby beds for us and many extra linens available for the chilly nights (heat was available but we were happy to bundle up).
The apartment itself is spectacular. If anything the pictures do not do the space justice. It's a large apartment with many antiques and some modern touches.
There were mosquitoes but our hosts had chemical plug-in repellent available to counter this problem. Overall they were not a big problem.
