I can only recommend a stay at Renzo's place. Communication with him was super easy and he was quick to respond. Renzo was also very accommodating concerning the check-in: I was supposed to arrive late at night which was no problem for him and when I missed my flight and arrived the next morning he had prepared everything for me so that I could check-in without him being there. Great experience! The apartment is stylish and very close to the train station. I attended a conference in the Palazzo dei Congressi and the apartment was conveniently situated between the congress center and the city. If you're a tourist you might want to stay closer to the city centre but for my purposes the location was perfect. Thanks for having me!
