When I booked the stay, I was told that there was a central location to pick up keys and store luggage, which was a huge convenience for us as we arrived in Florence before check in and departed several hours after. Unfortunately, they closed that office but did not inform me until I inquired the day of. We also could not check out later than 10 am or leave our bags.
Other than that, the apartment was beautiful and enormous. It was quiet but there was construction next door in the morning around 8 am. The man who met us to check us in was very friendly.
