Alessandro & Amanda's place was great! It is located within walking distance of the main train station in Florence, as well as all of the sites. My wife and I were able to walk everywhere and didn't need to take any public transit.
Alessandro met us for check in with no problems and gave us many recommendations for restaurants and gelato. We had the best gelato that we have had in all of Italy so far, as well as a fantastic sandwich from a local shop.
The room itself was great. The bed is comfortable and the street that the room is on is quiet and secluded. The only issue we had was that the shower would run out of hot water fairly quickly in the mornings, and the power blew a fuse 4 times in the three nights that we were there. It's very easy to flip the switch to put the power back on, but ask Alessandro to show you where it is quickly when you check in.
We had a fantastic stay here, and I would definitely recommend it to anyone travelling to Florence.
