We had a great time in Florence and Laura's apartment of was a big part of that.
Laura was very nice and welcoming! She had fruits, water and map waiting for us. The apartment has everything you'd need (dishwasher, laundry, drying rack, iron and ironing board, etc) and the bed was very comfy. There is no AC but even when it was hot outside, the apartment was cool inside.
Everything was within walking distance.
One negative is that the walk from the train station is about 10-15mins away and it's not fun with suitcases. Also the house numbers are confusing on the street.
Overall, everything was great and I would stay there again in a heartbeat.
