We had an amazing stay at Marco's place, his flat is absolutely amazing and the location couldn't be better, you can walk to all the main attractions and historic places.
He really took the time to think in every detail you might need while being on holidays at his flat: printer, portable wifi, city maps, amazing TV area, etc, etc.
I'm very thankful because we missed our train and for some reason our roaming wasn't working in Italy so he waited for us over 2 hours until we got to the place to do the check in. I would definitely recommend and come back.
