After reading all the reviews I was still a bit surprised to see for myself that it was all true. My husband and I stayed 4 nights, and the return on the train the first time can be confusing so he met us at the platform and drove us to his apartment which is on the first floor of a very clean, safe, and quiet building about a block from the train station and also from bus stop. My husband accidentally left his bag on train when we transferred trains and Mario immediately placed a phone call and then drove my husband to the train station to pick up the bag! Every day he would text us on the phone he loaned us to check in and make sure everything went OK. We really appreciate this as it is our first time in Europe and there are so many things that are different. Mario is thoughtful and really does whatever he can to make sure your stay is satisfactory. He provided a clean comfortable apartment. For the washing machine just read the booklet of instructions.
At the end he delivered us to our next destination in Florence. Thank you Mario!
