Marco and his place are great! He has clearly put a lot of thought into all the little considerate touches for his guests. Upon arrival he provided us with a list of his favorite restaurants and why as well as a map of Florence and things to do in the city. Once settled, we noticed along with a bottle of wine, Marco has left a recipe up in the kitchen for traditional Italian pasta and all the spices and ingredients needed to make it! So very thoughtful. And lastly, we had a bit of an issue with our car down a nearby, narrow ally and he was more than happy to come help us out of the tight jam! The place itself was very comfortable with fresh towels and linens -- basically 100% as described.
The only feedback I have for other out-of-towners, is if you're taking the bus into the city centre from Marco's place - make sure you buy tickets in advance. They do not sell the tickets on the bus and will ticket you 50 Euro. We found this out the hard way despite trying to pay when getting on the bus and not really seeing clear signage (and the driver told me ticket sales were 'done' for the day).
