The apartment was clean, equipped with everything you could need for a short stay (and more).
The location is great, Piazza Maggiore is a 10 minute walk away. Around the apartment you cand find shops, a pharmacy, pizzerias, bars, etc.
The communication with the host was great and fast. We had a problem with the wifi not working and they fixed it immediately.
Keep in mind that the train station is a bit far (30 minute walk), but there are bus stops near. And the walk itself is straight through the historic center, so it is a very pleasant stroll.
Overall, it is great value for money.
