I spent one night at B&B AMCollectionFlorence and I can say that everything is exactly as described. All the pictures are real: recently renovated, modern and nice fornitures, really comfortable bed and ensuite. The shower was perfect! Alberto is a very kind and helpful host. He personally prepare a really good homemade breakfast; I texted him many times to have informations and he always answered quickly. The location is so convenient, 5 minutes walk from the train station and 5 minutes walk from all the main tourist attractions (and the best boutiques of course). Lovely place! The only thing could be considered "bad" is that there's no elevator, but for me it was not a big problem as my luggage was really light..
I reccomend this place, sure!
