Enrico is a very helpful person, i was a bit late with arrival, and he made his best to meet me at place. He was almost always on phone :)

As for apartments,
pros:
* very close to train-station (5-10 minutes)
* a lot of shops to go, bars and caffe to visit
* very close to main sites - nearly 5-10 minutes to everywhere
* aparts were comfortable enough, but if it were air-conditioner it would be better
* comfortable kitchen

cons:
* as a first time to Florence i didn't know that apartments is on corner of the Main Market of Florence, but it could be a plus to other person ;)

good value/money
