I don’t think I’ve ever stayed at Westin but I love Sakura!
it is so hot in July I can’t even stand the 3-5min walk from Sakura to JR station. I always take the Limo Bus Directly from AC’d hotel lobby when staying at one of the Takanawa Hotels and heading to the airport in summer. Nights don’t get much cooler, but the sounds of night bugs chirping in the garden are some of what makes it so special to stay there.
