The apartment is in a fantastic location, right in Piazza della Signoria. Right in the middle of all places you will be visiting in Florence. About 20 mins walk to station. You can't go wrong with that. The apt. is furnished and has the necessary kitchen items for a couple of days in the city. The check in process was smooth. We were met with a host/manager who showed us everything about the apt., answered our questions and shared information about places to visit and eat. She also found out information on car rental and buses for us.
The apt. looks bigger in pictures. Its a lovely clean apt. but has its quirks which can annoy you. The second floor/loft has very low ceilings so an adult cannot stay there. I had my 2 young teenage daughters in there, and even they hit their heads every now and then. Similar type of issue for the bathroom in the main bedroom. It was 4 steps down and you had to bend down to go in so you had to be careful going in there...hit my head a couple of times. The shower was a bit slippery. The sofa bed would take up the entire sitting area so not much space in there. The washer / dryer are in a common area outside of the apt, not in the apt.
I would recommend staying here for location for a couple of days and if you do not have a large group. We were a family of 5 (2 adults, 3 teens) and found it to be tight
