Here's the short version: look no further. Stay here. Gabriele is an amazing host and the house is perfect.
Here are some details:
1. Gabriele is a wonderful host. He picked us up from the airport and even left a small welcome basket to get us started for our long stay.
2. He emailed every week or so just to make sure everything is ok.
3. Whenever we had questions or requests, he responded quickly. For example, we were worried the washing machine wasn't working. (We're Americans and were expecting it to go for 30 min. European washing machines go for a lot longer.) I emailed and Gabriele popped over a little while later to check it out.
4. The house is VERY close to public transit. It's a 13 minute tram ride to the city center.
5. The vino sfuso seller up the street (towards the tram) is fantastic.
6. The bread baker (5 minute walk away from the tram) makes the best schiaccatta toscana in town.
7. Gabriele is full of great advice for getting around the city. He'll point you towards grocery stores, banks, whatever you'll need.
In short, Gabriele is one of the best hosts I've ever had the pleasure of working with. I would stay here again and I would recommend it to all of my friends and family.
