The apartment is just as it appears in photos, it has a large living area, kitchen, and bedroom; additionally there's a small loft with a twin bed. The neighborhood is fantastic with dozens of bars, restaurants, stores, grocery stores, and squares to hang out in. It takes about 15-20 minutes to walk to the city center in florence from this location. While the apartment is located on a busy street, it's pretty quiet as it's located on the third floor.
A few notes:
1) The street is pretty busy and opens within inches of traffic, this is a little difficult with dogs or with young kids. If you're careful, it's totally fine.
2) Parking, you do not want to park in florence. There's a park and ride system about 20 minutes outside the city via tram. Use this, if you have a car. It would be a miserable experience driving around and parking anywhere in Florence.
3) The Westin's rooftop bar is amazing and it's a ten minute walk. It's really expensive (about 15 euro a drink) but worth it at sunset.
4) Make dinner reservations and definitely try the sour dough pizza place that's about 5 minutes from the apartment.
