We spent 24 days on the Diamond Princess, two back-to-back cruises. The quality was Princess standard, very good but not exceptional. My comments will focus on what we did rather than the ship's features.
First, the cabin. We had E633, an obstructed view on Deck 8. It's a good cabin. The window is between two lifeboats, so the view is relatively unobstructed. The cabin door is right across from a stairwell, which worried me at first, but the incoming noise was minimal. There was no noise coming from the Promenade Deck below (other than occasional loud walkers). We liked it a lot. It was convenient to the Promenade Deck (we like to sit and watch the ocean go by) and to everything else.
As platinum members, we appreciated the fact that the Skywalker Lounge was often reserved for us. It was a great place to read, and the evening drinks before dinner were pleasant. However, sometimes they had it closed for private functions, somewhat disappointing.
