Massimo's home is in a great location, about a five minute walk to the train station. There is an amazing restaurant right around the corner from his home that I would highly recommend. Plenty of coffee shops and stores to go into. From the main tourist sites, it's about a twenty minute walk, but may be quicker by water taxi.
As for the home itself, it was cozy. It is a great place to lay your head down at night, and wonder the city during the day. There are some pans to cook with and plenty of dishes to eat on. Would recommend.
Massimo is very accommodating. We got in a couple hours earlier and was able to check in. We also had a little mishaps with the washing machine and Massimo came right over to fix it for us. He is a great host.
