My wife and I had a pleasant stay at Donatellas apartment. The room was fantastic, ensuite bathroom great and all very clean and the aircon was a lifesaver. The little terrace was great to look out over florence and the duomo. We had good communication from the host and they let us stay longer after 10 AM checkout as the cleaner was running late which helped us greatly.
The best thing was the location, it is very well situated in the heart of Florence. The interaction with the host was infrequent during our stay but we felt we could ask anything and they would have given the time to answer so that suited us perfectly. I would recommend this accomodation to other couples or singles for sure.
