My wife and i were traveling to Italy for 2 weeks and stayed at Sally’s house for 3 nights. Sally and Sean are very positive, welcoming and flexible guys!
They explained how to reach their house and met us at the time we needed (1pm). The place is 20min walk from the train station on foot, or you can take the tram and reach it in 10 min.
The room was simple, comfortable and nice. It was hot (August), but with the fan it was quite nice. Coffee, tea, cookies, bread, jam, butter, honey and cotton cheese were always at our disposal.

Sean explained us everything – the transportation system of the city, how to reach this or that place, what is worth visiting, where to find delicious food. Sally and Sean are very interesting and intelligent people and it was a pleasure to have nice conversations with them in the kitchen in the evenings (education system, culture, architecture) :)
If you want a simple room that is not that far from transportation hub (Santa Maria Novella) with very good and flexible hosts, definitely book it!
Thank you very much guys and wish you all the best with your plans!
