I did not meet Katia during my stay but Cristina showed us around the apartment and made us feel very welcome. She also gave good recommendations for places to eat. Il Latini was great!!
We loved the apartment. It is large and spacious and had everything we needed for our weekend. The best thing about the apartment is the location, just off a small street only 50m away from the Duomo. Unfortunately the weather wasn't too good during our stay, otherwise I would have never left the balcony.
I will definitely return in the future to visit all that I didn't have time for this time around.
