Well ive never really had any insanely nice rooms, cant afford the suites, but im easily impressed with nice basic rooms
1) Basic room at the new W Taipei, went a few days after it opened for 1 night, loved the design, very modern and minimal, great view on an upper floor, loved the back lighting and the brand new BMW 7 series that picked me up at the airport
2) 4 points Milan, checked into our hostel and it was horrible, called SPG, booked basic room from the cab, got upgraded to a club level workout room. Great high roof, tons of molding and great woodwork. Rainfall shower, bathroom was 3 mini rooms in itself.
3) Sheraton Norfolk, upgraded to a nice corner suite, little patio, nothing amazing, but plenty of room to walk around and unwind. Only downside was being woken up at 7 AM by the people in the next room going at it...quite vigorously......
