This is a tidy, clean, air-conditioned apartment.
It is very central - an ideal location - though this does come at the cost of some noise on the streets below. I would say this is the only drawback to this property.
It has good wifi, a fridge where you can keep your bottled water cool, and a good bathroom (the shower is a little on the small size - but has a great shower-head and water pressure).
In the building, there is a small lift so you don't have to worry about carrying luggage up and down the stairs. I would say that it took me a while to find the light switches in the building stairwell (the lights turn off automatically after a short while and there is no other source of light in the stairwell) - they were almost identical to the doorbell switches, so we may have accidentally rung someone's door bell once or twice whilst fumbling for the lights.
All in all, I would definitely recommend this to anyone looking to visit Florence, and would most likely look to stay here again should I hopefully return to this beautiful city.
