Jacqueline is a wonderful host.
The location is absolutely outstanding offering perfect access to key sights like Duomo and Academia with little to no extra walking. Plenty of restaurants and shops nearby including grocery across the street.
The unit itself has tremendous character and the terrace is a perfect way to enjoy a light breakfast or glass of wine in the evening. Watch your head in the bathroom and remember as this is a top floor and there is no lift, well worth the view and noise isolation but you will be talking some extra steps to work off that extra glass of Chianti or bowl of pasta.
