When visiting a city to interact with it, learn about it, jump into history, art, or vibe, location is key. Elio' place has location nailed. In my opinion there is no better location for home base in this city.
Next, for liveability, this place also gets 5 stars from us. We found groceries nearby easily, so we ate in each day for breakfast and dinner, and ate lunch and evening snacks and desserts out, with so many options for that literally just outside the door.
Transit is a snap, including the fact that so much is walkable. The flat is cute, comfortable, and thoughtfully appointed. Elio' instructions are clear and he's reachable.
For advice: don't forget to sit back and enjoy the flat and the neighborhood a bit!
