There's a distinct difference between A and B. Fortunately, having booked 2 rooms, my travelling companion got the 1st floor in Block A. Scrumptiously beautiful. I was given a ground floor in Block B. It was a one-night stay and great if you wish to sleep in. However you'll miss a great breakfast. I was shocked by how dark my room was, and for a second night, I would have needed to move. Utilitarian and basic. The breakfast room in Block A, is splendid, as is the selection for breakfast. Fresh juice. Fresh coffee.
