This is the best spot you can get. We loved our location. What an incredible view of Il Duomo. We fell in love with Florence and this airbnb was wonderful.
Only issues:
1) Queen size bed with two twin size mattresses combined. This was very uncomfortable for my partner and I. the mattress kept slipping and we'd slip into the crack
2) really unconmfortable couch with cushions that kept slipping and you could barely sit on it.
3) TV was useless.
At the end of the day, you visit florence not to stay in your Airbnb. This location and spot is wonderful and the host is great so they still deserve 5 stars for me.
