I spent a few weeks in this wonderful place. Do not doubt. It is as good as it looks. Even better!
The whole place is full of charm. Guido is always helpful, fun to have a talk and never intrussive. The Capella is the most particular place. The large gardens around the property are amazing. The entry all along the way sourrounded by pines with the villa at the end is just magical.
The place is at the same time isolated but perfectly connected with the city. It really feels like being in the wonderful country villa of the Strozzi family, in the wonderful florentine hills. But at the same time, you can see the Brunelleschi's dome while having breakfast below the large wisteria outside the capella, and get there just after a 10 min walk to take the bus. In total 30/40 minutes.
Just walk around the little roads up and down and you will reach Michelangelo's birth house, wonderful villas, the best views of the city...
It doesn't get much better than this in Florence, and for a price that is so reasonable.
