LOCATION! That is the best thing that comes with this apartment. We were able to walk to all the main tourist attractions, and basically everywhere because of how centrally located this apartment is (all within 10-12 minutes walking distance). Point to note, because of the location of this apartment, you will not be able to get a taxi to come pick you up. Honestly, just reserving a taxi service in general was just so hard, we had no choice but to walk everywhere, even to the train station, which is only a 16 minute walk, but with all our bags (and we have a baby), it was a little difficult. So, that was a little inconvenient.
Besides the taxi situation, I do have to agree with the other reviewer, that the apartment is a little bare-boned. They did a good job decorating the cozy apartment and it's really cute, but some basic things in the kitchen, like paper towel, or dish rack would have been convenient, and a shower gel in the bathroom, an ironing board, and even a smart TV would have been a nice touch, especially since it's a newer apartment (but that's not a necessity of course).
Honestly though, what I listed above isn't even that serious because Alessio, who was our host, was just SO amazing. I'm sure if I asked him to bring us paper towels, or anything, he would have done it. He was the most responsive Airbnb host we have ever had. He will respond to you within minutes, no matter what time it is. He even tried so hard to help us get a taxi, but even he couldn't get a hold of any. A host going above and beyond is a 5-star in my books! I would definitely book this apartment again if we ever get a chance to come to Florence again. Thanks so much, Alessio!
