Overall - Awesome experience, super convenient to Muckross House/Farms, very clean and roomy, easy to check in, and friendly host
Sheila's place is a short drive away from Muckross (probably a few minutes). It's incredibly convenient if you're visiting Killarney National Park.
Checking in is also very easy. Keep in mind that "Alran Heights" is the name of her place, and the mailbox is marked as such. My dumb Yankee brain automatically assumed it was an entire area, like "Boyle Heights" or "Rowland Heights." There was plenty of parking on her property as well.
Sheila was very friendly and easy going. The room was very clean and had everything we needed. En-suite rooms are simply the best.
Will definitely be back.
