This is a great apartment in so many ways. The location is amazing. You are right in the heart of Florence, but feel "tucked away". The locailty has some wonderful restaurants and bars and the south side of the Arno is definitely worth exploring. Monika gave us a restaurant tip which we took her up on and were treated to a very nice meal. There are some top notch restaurants within walking distance as well as cheaper options too. Gino's cake shop seems to be open all hours and there is a great supermarket about 250 m away.
The apartment is spacious with TVs in every bedroom and the living room. There is air con in each room which is effective. The washer and drier in the basement are really useful. The walk-in closet is great and really handy for a longer stay (we stayed for 3 weeks).
The apartment is beautifully appointed: stylish bathrooms, a great kitchen, comfy sofas, good amounts of crockery. It is spacious , and while we were only 2 staying there, it would easily take 6 no problem.
We did enjoy seeing people taking pictures of "our" tower and it was fun trying to spot it from various vanatge points round the city.
Downsides - occasional late night mopeds and noisy revellers (but it's a fun area so not surprising!)
