We had a great stay at Ella's Inn. They were very friendly and made sure we're comfortable. Unlimited hot and cold water was very helpful. The dogs are wonderful too - we find them funny.
Tip: Just be sure to tell them that you're arriving late at night, tell them exactly around what time, so you won't end up locked at the gates. We were the only guests there, and the caretaker (owner?) bought food outside so the gates were locked when we arrived. It was okay as we just waited for around 5 minutes. Not a biggie.
The guy caretaker was so wonderful, he gave us tips on interesting places around Ipoh and nearby areas. Highly recommended for those who have a car!
