Excellent place, location, style and hospitality.
Very central, literally 5-10 min walk to Duomo (depends on how fast you walk).
The photos are an accurate depiction of the actual space.
Giacomo and his friend, Taylor, were on site to receive us upon checking in (despite us being late due to traffic otw from Lucca). They helped with carrying our bags and were very kind to walk us through the apartment as well as provided a tourist friendly map of Florence, pointing out the best places to eat, shop, see (btw, best Gelato in Florence is located at "Perché No"... trust me, just find it on Google Maps)
There was a traditional coffee maker as well as coffee powder, which allowed us to make fantastic coffees in the morning.
Just remember, that there are 4 flights of stairs to get up to the apartment. It's not that bad at all (it just sounds a lot more daunting), but you may run into some trouble if you have 4 or 5 heavy suitcases to carry up and down. But if you coordinate your check in time with Giacomo, he's very helpful with the luggage. Other than that, no problem at all.
