We were very happy with this place. The apartment was very spacious; it was equipped with everything we needed. The kitchen was probably one of the best equipped kitchens we have seen yet, and there were other essentials that were helpful to have, such as laundry detergent. We really loved the balcony too. We spent every night out there drinking wine while our kids were asleep. The air conditioning was a life saver because we were in Florence during a heat wave.
When we arrived, we were greeted at the apartment and shown how everything works; in addition there is a map and guidebook with recommendations of places to go.
The location was ideal. It is a 10 minute walk from the Duomo, but yet on a quiet street that feels out of the tourist path. The train station is a 15 minute walk away, and the grocery store is a 5 minute walk. This was really helpful for our family because we could come home mid-day and get out of the heat.
The only thing we want to warn you about is the Wi-Fi service. It is a little spotty, and at one point we had to reset the router. This really wasn't a big deal, except that we weren't aware we weren't on Wi-Fi and ended up using up the data on our SIM card without realizing it. We would recommend setting your phone to warn you of a Wi-Fi disconnection.
