A very clean, quiet apartment with a balcony that looks out onto a large central courtyard, which meant it was very quiet in the evenings. Francesco is a great host, he was very efficient at communicating with us and made sure we had everything we needed. He was even able to meet us at the airport and take us to the flat.
The apartment was fully equipped, with wifi, kitchen, fridge (with cold water bottles inside), washing machine and line (very useful as we went to the city beach a couple of times), a/c, abundant coffee, condiments etc. It was quite roomy for four of us, with a sofa bed in the kitchen/living room and another spare sofa bed in the bedroom. Really roomy for two, comfortable for four, manageable for six sleeping in pairs.
The apartment is about 15 minutes walk from the commercial/old centre, and, in a different direction, the central station - the street it's on is not so interesting for walking along but the next street up, Dante Alighieri, is much more tree shaded and pleasant.
It's not in the really posh part of town or the touristy old centre, but that wasn't a problem as walking to those places was easy.
