I went at the end of March with 4 female friends. 3 had single rooms and 2 shared a twin. I had been there before on my own and had suggested it. I was therefore a little nervous as to whether it would be as good as I remembered. We weren't disappointed at all. The hotel was lovely. They have the best appointed single rooms I have ever stayed and the free water in the mini bar is a really lovely touch.
We were lucky with the weather so made good use of the rooftop bar. Breakfast was lovely and the location is absolutely perfect. For such a central spot, the rooms are very quiet. It is a four star hotel and can seem expensive at first glance. They often have special offers on if you book direct through their website and we got a really good deal. The twin was just over £100 per night for the room incl breakfast and the single cost about £250 for 3 nights which is really good for such a high standard hotel.
I don't think i would actually stay anywhere else when i go back to Florence.More
