This is a really great and authentic apartment in very central and easy-to-find location. It has many amenities, is spacious and comfortable. Paolo and Roberta were very friendly and helpful.
There is one thing to keep in mind - this is more of an "hotel experience" than and Airbnb, where the hosts enter the apartment to tidy up, clean, open/close windows, etc. while you're out, without warning you first and it might be a bit surprising if you expect to have "a private property all to yourself".
Other than that we would definitely recommend it for short or longer stay.
