The trouble with that, is the book is, at minimum, 18 months out of date (by the time the reviewers have stayed, written up, published, to book shelves etc.) I bought a few books on Amazon last month, and the latest update for several of the well known ones were 2-3 years ago. Plus, you have a very limited sample - perhaps just one stay - which as we all know can go very well or very badly - a mass sampling will probably give you a better overall idea IMO.

I like that TA is current - there are people who were there last week, so they can give you almost real time information. If you venture into the forum side, there are people who post 'live from' threads.

It has its limitations, sure. But it can also answer the questions on things that are important to you - beds hard or sort? Shower curtains, or glass dividers? What sort of coffee is in the rooms, etc. Things that don't make it into more formal publications, yet may have burning importance to you.
