First of all I wanted to say that Marcella and her husband are very friendly and ready to help. And thank you so much for everything you have done for us!
The location of apartment is great, all main spots are in walking distance: 12mins from central bus/train station, 20mins from historical center, 7mins walk from shopping street.
The apartment is cozy and modern. There are everything we need (except of an iron, but it was not so important for our stay): fully equipped kitchen, bathroom and super comfortable and beautiful bedroom. The only one issue: it was a bit coldly for us in the flat, but it is normal for Italy. So take a wool socks :)
The city is so lovely, we have enjoyed our trip!
