Ada' flat is possibly in the best location, right in the heart of Florence only 5mins walk from the train station, next to Piazza de la Republica. very clean, cozy, excellent for a few days in Florence. If you like shopping it is a must. ada was kind enough to wait for us as we were late, very polite and helpful. The only comment I have is that at checkout although I notified that we were going to leave between 10,30-11,30 ( which I think is a very reasonable checkout time), Ada told me that the cleaner would arrive between 10-10,30 which was a bit awkward and made us leave in a hurry. Overall an excellent experience and highly recommended, would definitely stay there again.
