Apartment locatiion is amazing!
You are right in the middle of the old town! Duomo is in a 5 minute walk and there are a lot of great restaurants right outside your door. Beware that because of that it's not super quiet at weekend nights if you want to sleep with your windows open, but it is not a big problem.
The apartment itself is clean, nice and surprisingly spacious because of high cellings. Wi-Fi was fast and water pressure is great.
Alessandro was very punctual and helpful.
All in all - amazing apartment for the affordable price.
