Andrea, Luca and Gianluig's place was everything we had dreamed of it to be and more. Saying this considering that our expectations had already been high to begin with!
The location of the place is just the best you can get in the city centre (=old town) in Florence. The Academia, where you can see Michelangelos "David" is actually just across the street, and everything you'll be wanting to see is easily attainable by foot.
The flat itself is setup beautifully and with an amazing eye for detail, as you can see on the pictures.
Information about the city, tourist maps and stuff, is provided - though we didn't need it 'cause we knew the city beforehand. The supermarket is very close, and the kitchen is well equipped. Makes it fun to prepare your own food, if you wanna do so.
The bathroom is comfortable and clean.
Communication with our hosts was great as well. We didn't get to meet them in person, because everything (getting into the apartment and stuff) works without them being there personally, - which maybe is not the preferred option for some people, but for us it totally was - though via text messages & co. they appeared like people who'd be lovely to meet. :)
Would book it again everytime. And probably will.
