I would fully recommend staying at Tommasos place!
It had beautiful big windows with a nice view, high ceilings and lovely cool air conditioning (we were there in July).
We were traveling with our 2 year old daughter. One good thing was the washing machine to clean her gelato and pasta stained clothes. Though we wouldn't really recommend the place traveling with small children, because it's on the top floor and no elevator. But if your up for some exercise go ahead! :)
Tommaso was an excellent host! Quick to answer e-mails beforehand and very quick to help when we had a question during our stay. At check-in he gave us lots of useful information about the apartment and about the city.
Thank you, Tommaso!
