We definitely enjoyed our stay here. To start the trip off, our train arrived a bit late, but Mario stayed 20 minutes later than the posted arrival hours so we could check in smoothly. After that he took even more time to give us a map and outline all the cool things to do in Florence, the best bus routes to get where, a nearby affordable restaurant, etc. Throughout the trip he also checked up on us to make sure everything was going smoothly.
The place itself was also great. It was only about a mile from the train station and the heart of downtown. There's an easy bus line, or a 20ish minute walk to get there. The room was big and clean, it had a patio and a private bathroom. They also provided a cup of much needed coffee per guest each morning.
Overall, I'd definitely recommend this place!
