The Sheraton Grand was my go to for many years in a good area, then Les Suites Ching Cheng, which has a happy hour 1700-1900, free pour coffee 24 hrs and again well located. The Westin featured the best breakfast I ever had and was not far from Ghengis Kahn Mongolian BBQ, sadly both have closed now, with the Westin becoming a JR Hotel, Hotel Metropolitan Premier Taipei
