Let me start with the good. Federico's place is perfectly located close to all kinds of wonderful parts of Firenze. Everything was within walking distance and nothing you could want to see inside of Firenze was more than a mile away. The unit was beautiful with the frescoes and the building it was inside of was almost magical with its enormous wooden doors and iron gates straight out of the 15th century. Federico's sister helped us into the house and was a great assistant in finding some good local things like the closest grocery store and some of her favorite gelato places.
Now for the bad. This is clearly a new acquisition meant just to be used for AirBnB and some of the kinks haven't been worked out. The biggest issue was the washer which was advertised but could not be used because the wiring for it had never been hooked up. Federico was willing to send an electrician while we were there but quite frankly, I didn't want to spend my vacation waiting for an electrician to show up. I can do that just fine at home. The kitchen was clean and big and new but also missing some basic kitchen utensils and equipment like a cheese grater and colander. The dishwasher was also unwired like the washer so dishes were done by hand (though I don't recall whether the dishwasher was specifically advertised).
All in all Federico was a good host and made efforts to address my complaints and I am sure that these problems will either not be noticed by people there for shorter durations (we were there for 11 days) or will be fixed in the very near future.
