The apartment overall was a good experience despite the couple of things that were off about it. This was due to our great host, who was extremely communicative with us and gave us complimentary extra days for our trouble.
The downsides of the apartment were big for us, but probably minor for other people depending on how you stay there. The internet connection left a lot to be desired (frequent disconnections and slow speeds) as well as the apartment not looking like it did in the listing images.
For context, my girlfriend and I work remotely abroad so we rely heavily on the strength, speed, and consistency of the internet connection. The internet here would very frequently get really slow and sometimes disconnect altogether. It was not suitable whatsoever for remote team calls and downloads, video streaming, etc. We had to buy a hotspot to accommodate for this.
Secondly was the listing photos - these appeared much better than the actual apartment. It showed nicer furniture and a different layout. The apartment in reality was still decent but not as lively as the photos.
Overall, despite these 2 issues, we had a great time and it was very well located in Florence.
