I stayed at the Chateau de Chine in Aug 2013 for one night. This hotel is being re-branded. The lobby looks great. My room was clean but a bit dated. The breakfast was very good. Dinner looked good but I ate off the property. The hotel has a three washer/dryer combos for a quick laundry run. The only issue with the room was there was no room safe.
In short this hotel was a reasonable choice for a business stay in Taoyuan.
