Imbeliveble: Library Hotel is Trip Advisor recommended!
I was at Library Hotel on July 2012. In my opinion it is really umbeliveble to recommend this Hotel, especially with a trip advisor Excellence certificate! 
The rooms were so small (you can not sell as double a so small bed in a very very small room. It is better forget the bathroom) and all the furnitures were old (the plug does not go, the light were brooken, ecc.). 
The breakfst was really poor (they refused me also a scramble eggs, even paying it).
The last night of my stay, I discovered that my nightshirt was disapperead! I asked in the morning to the reception: the unpolite reception manager told me: Are you sure that you do not find it? Afther my complain, they noted it and they sended me after one week my nightshirt in Italy durty and in a very bed conditions, without a card just to say "I'm sorry".
Honnestly I have to note that the reception staff was kind and helpfull and the location was good.
But you can not think to pay a very high rate to stay in a so poor and cheap Hotel.
It is not enough to show some book to hit the guest!
I never come back to Library Hotel.
