Staff probably one of the best I've ever encountered, beautiful common areas, cozy, very well appointed rooms (standard rooms are a little smaller than advertised, but still lovely), super comfortable beds, excellent breakfast (worth it even if not included in your room rate), nice spa area (in need of a face lift though - see minuses) and a great, quiet, super central location. One of the nicest hotel experiences overall - would definitely come back.
Parts of the hotel are in need of a bit of a face lift. It's perfectly lovely as it is, but to elevate the hotel to true, world class 5-star status, common areas, particularly the gym and the pool area should be upgraded and updated (tiles, lighting, candles, flowers etc.) It would also be lovely if breakfast was served in a more airy, spacious setting (it's in the basement right now). Sound proofing in rooms could also be better (you hear what goes on in the hallways right now.) These are minor points though, overall the hotel is fantastic.
