My wife and I stayed at Loredana's place for 4 nights, and I have to say it was a really fantastic experience ! First of all, all of the communication before our arrival was excellent - always timely and informative. When we arrived at the place, Stefano was waiting outside for us, and once we got inside he spent a lot of time telling us about the area and going through all sorts of recommendations about places to go and things to do - they were all very accurate and excellent places. The apartment itself was awesome - really large, beautifully kept, well equipped and in such a great location. This was the 4th place we stayed during our travels and definitely one of our favorite spots.
If you are making your way to Florence, then I cannot recommend this apartment enough - we had really high expectations and it even exceeded those !
