Pietro was very welcoming - our plane was later than expected so we had to wait for last bus to centre but Pietro welcomed us even that late, thanks!
The apartment is in great location, in city centre, about 1 km away from railway station, just a few minutes walk from shops. Alta Citta is also reachable by feet.
The best part is the little balcony, perfect for evening when the sun shines on it :)
Just be aware that there is a restaurant down at house so it can be a bit loud at late evenings.
But overall I would recommend staying at Pietro's place, it is a good place for couple.
