My girlfriend and I had a very pleasant stay at Casa Ambrogio and would absolutely recommend going there.
The apartment was clean, spacious, comfortable and well furnished. The kicthen had everything we needed to cook and all the products to clean it were already there.
Germana was very friendly and helpful, when we arrived she explained us everything about the apartment and gave us suggestions for bars, restaurants and typical trattorie.
The location of the apartment was also good, far enough from the historical centre not to be crowded with tourists, but close enough to be able to walk anywhere!
