Giada's apartment is just how it looks in the photos. It was clean and comfortable, and the perfect size for a couple travelling together. All of the amenities (shower, WiFi, etc.) worked well and we found it very pleasant to stay there.
The only thing some might find annoying is that the sound in the courtyard outside echoes and can be very loud. The neighbours had family over when we were there, and the kids made a lot of noise! That said, they quietened down after dark, and we slept just fine.
The apartment is ideally located to visit all of the major sights in Florence. We walked everywhere - it's literally minutes away from the Duomo and tons of great restaurants. Highly recommended.
