I visited here in July with my girlfriend. While we enjoyed the romantic nature of the hotel away from the rush of the city, there was nothing to do in the area, and little to do at the hotel other than dinner and drinks. The restaurant and bar are the best points of the hotel. The food served is exceptional, and the barman is a charmer. (My friend enjoyed his humor and attention especially, as did I.) Their so-called spa is basically non-existant, their grounds are oddly spaced and rather useless, and their swimming poor is odd and nothing that lends itself to actually swimming inside. I have since re-read a few of the negative complaints, and I can agree that for a family with kids the swimming pool is likely far from western safety standards and best to be avoided. The staff was okay in total -- the maids were charming, the restaurant staff were exceptional, but the desk staff were rather bland and humorless.
In total, for those who understand and appreciate world class resorts, the Hotel Mulino di Firenze
is far from top notch. On a value scale it is even worse.
