I stayed three nights at Paolo & Daniele's place and really enjoyed it. It's a very nice, comfortable and stylish split level apartment situated within a nice and secure building block. Easy place to get anywhere in Florence. Less than 10mins by bus (No 17) to get to the central train station from where you can start exploring Florence as all is within walking distance. Supermarket & bus stops are just minutes away. There are also local restaurants, shops and a cafe shop with a vast selection of pastries ( in from of a bus stop). You can buy bus tickets at a local tobacco shop on the way to a bus stop.
Daniele was a great host as he sent a message every day to check out whether everything was okay.
I would recommend Paolo & Daniele's place.
