I haven't stayed in the PH Tokyo, but I liked the room I got in the Andaz. What I really liked was the free soda in the room. if I drank some and went out i'd come back and they would be replaced. Andaz isn't an option for me at this time unless award space opens up again closer in, but on the weekend the area was just too dead. Sometimes you just want to go out and see something without having to take a train. Sadly my understanding is the PH is kinda isolated as well, but maybe you can at least walk to somewhere interesting.
