their small print says they just act as agent for the hotel and your contract is with the hotel. I don't see how they can offer you another hotel in the first place? Sorry, I don't have any experience with them; before I book a hotel online I check them out on tripadvisor and check their own website; that seems the best way of finding out about things like refurbishment. As far as your legal situation goes, perhaps you could post a copy of this question in the Law section, you might get more knowledgeable answers than I can give you. Apologies.
