Great stay at Edoardo's apartment which was as described and like the pictures on the website. Lovely and very clean!
As mentioned in the comments, the only things to know are that it is located in the basement (but with windows) and that the neighborhood can be an issue to some people (but we never had any problem).
Special thanks to Francesca who was really welcoming and provided us with good tips. She was also very available and we could call her whenever we wanted as she told us.
