Staying at Via dei Cerchi 11 was the most wonderful experience! My 4 friends and I were greeted by the owners daughter who gave us the keys and showed us around the apartment. It was exactly as depicted in the pictures and descriptions. There was more than enough room for the 5 of us, even 2 more would have been comfortable.
For anyone who has never been to Florence before, there were a ton of adaptors, maps and guides left behing by others. The apartment also has an abundant amount of towels, kitchenware if you want to cook, and even a bottle of welcome wine!
The apartment is in a perfect central location to everything and has an amazing view of the piazza below (complete with beautiful live music from accordian players) as well as the bell tower beyond. Another good thing is that the building is full of offices, so nobody else is in the apartment at night to be bothered by loud noises if you're coming in late. Another plus is that there was AC and wifi--you can never go wrong with that duo.

I have no reason to not recomment this awesome apartment! It was like home to us for 6 days and we're so glad to have been able to stay there.
