Piero's place is great, much bigger than I expected. A nice beautiful apartment. It is just outside ZTL with a parking space. It worked out perfectly well for us with a rental car.
Piero was very nice and thoughtful. He met us downstairs and directed us to the parking log. He showed us every single thing in the apartment, and information about bus/taxi. And later one he also answered my questions about good local restaurants.
I didn't get a chance to meet him again before we left. But here I want to say thank you to him again and highly recommend his place.
