Lovely clean, quiet apartment on the south bank of the Arno river. Perfect for 1 or 2 people. Easy walking distance to all the sites. I preferred this side of the river because it's quieter, yet it's still easy walking distance to everywhere in Florence. Just a 5 minute walk to Boboli gardens and a 15-20 min walk to the Duomo plaza.
Comfy bed, nice modern bathroom, fully equipped kitchen, and even a washer for your clothes (when I was there there wasn't clothes detergent so you may need to buy your own).
My contact Sarah even called a taxi for me when I left since I had no international calling plan. Nice!
The only issue for me was the a/c. There is one in the living room and it works, but you won't have control over the temp or high/low settings. It's set to a low output by default and the bedroom was warm in mid August.
Everything else was excellent and I would definitely stay here again!
