Location...location...location! This apartment is nothing short of spectacular - the location, the views, the amenities are all top notch. The apartment has 2 bedrooms, 2 full bathrooms, air conditioning, a washer and a dryer (yes, a dryer), drying rack, iron/iron board in the unit as well a very well appointed kitchen (including a Nespresso machine and dish washer). The TV (if you care to watch) has Netflix. The building has an elevator and there is a taxi stand right outside the front door (the Hotel Savoy is around the corner too if there isn't a taxi there). You can walk easily from the train station in 10-15 mins. The pictures in the profile are completely accurate. If you open the bedroom windows, the Duomo is right there - really cool views during sunset. Often there were musicians playing in the evening so you could just open the windows and listen. From the apartment you can pretty much get anywhere easily by foot. We spent 10 days there and ate in places throughout the area, we didn't have a bad meal. The check in process and communication throughout our stay (and before) with Lucca was extremely efficient.
There is absolutely nothing we can say negative about our experience. We will absolutely return on future trips to Florence.
Note, if you are not use to sleeping in cities or historic centers of cities, then street noise might bother you. BUT there is an easy solution (and one we have used regularly throughout our travels in Europe) - buy a small white noise machine and toss it in your luggage (maybe ear plugs too if you are a sensitive sleeper). With the portable white noise machine we've never had any issues and we didn't during our stay here either. In general, that is just the trade-off of staying in the middle of the historic areas throughout Europe (which is 100% worth it).
