You seriously can't beat this location. First it's literally steps from the iconic Duomo...literally like 2 minutes away. So this means you are basically in the middle of Florence. The furthest we walked was about 40 minutes to see the rose gardens but that was absolutely worth it. It's also about a 10-15 minute walk from the train station and close to a lot food options. Simply based on location this should be your pick. It also has an elevator which is amazing.
The only thing that was a little weird that I didnt realize was that laundry is shared with the floor...like 3 or 4 other apartments for one washer. So we didn't end up using that.
Overall the apartment is lovely. Simple kitchenette area, dining/bedroom area and a huge balcony. Plus the bed was comfortable!!!! We've been traveling for like 2 and half weeks, doing all Airbnb and having a comfortable bed was amazing and so refreshing.
