This is one of the best hotels I've visited in Ethiopia - far better than what is available in most towns outside Addis. Details are catalogued thoroughly in older reviews: spectacular views from every room, unique modern architecture, great food, etc. Two additional notes: 1) I had no trouble booking a room via email. 2) Hotel has complimentary airport transfer - don't make the mistake I did and ask your tour company to provide it (for additional cost).
This is such a nice hotel, it's worth adding a day to your stay in Lalibela just to enjoy the views, nice food, and beautiful surroundings.
