Marco's place is one of the best airbnb that i have stayed! Its very convenient, right next to the train station and grocery store. Most of Florence's attractions are also within waking distance.
Facilities - it is more well stocked than my home! For example, the kitchen had a full set of pots and pans, moka pots, in addition to cooking spices and snacks. There's also oven and microwave if you want to cook.
Details - Marco paid a lot of attention to the details as there's emergency first aid kit, sanitary wares stocked in addition to water in the fridge.
If i were to point out a downside, it will be that the electricty may trip if you use too many appliances at the same time (not the fault of the owner, as the building is built many years ago with the frienzed ceilings), you have to go down to the first level to reset the electricity box. But well, the age of the building does add charm to the place.
Overall its quite a cozy place that is value for money in a central location.
