We stayed for 2 weeks and it was everything we needed (with many small gifts such as chocolate, honey, wine and more (it really felt generous and not that common in Airbnb apartments). Claudia was very very kind and assisted with small things that made our stay easier :-)
The apartment is spacious (we were 2 but since there is another spacious bedroom 3 will find it also great). It is cozy as well as very stylish and beautifully decorated. It is super clean. It is a quiet neighborhood so it's a slightly longer walk to some of Florence attraction. Around 25 minutes’ walk to the Uffizi for example (but a great walk either on the river or in the beautiful streets). We sometimes took bicycles and then it was only 10 minutes.
There is a big Conad supermarket 5-7 minutes’ walk and various other shops for buying things to eat or cook. The only thing important to mention is that the Kitchen is a bit small (although fully equipped), so if you plan to cook meals at home, bear that in mind (we did cook every day).
