Lovely quiet neighbourhood, great view over the Shannon estuary. Yvonne was very welcoming and even offered to look after our children while we went for a meal. The apartment space is fairly small for 4 people, but quite manageable. Double bed was very comfortable; the two singles had soft mattresses that were absolutely fine for the kids but may not have been so good for adults. Pretty much everything you could need was in the kitchen, plus plenty of towels and pillows to get comfortable, and some options for breakfast, which was great as we arrived late.
Wifi worked perfectly the whole time we were there.
Location is very convenient for Shannon (and airport) and Limerick, and there are local shops and restaurants very near, including Gallaghers in Bunratty, which was superb.
If you want beaches, the best ones are a fair drive, but you do have the option of going to those in either Clare or Kerry. Plenty of other things to do and see within reasonable distance.
Downsides: the bedroom windows are set in the roof so don't have lightproof curtains, which can be an issue if you like a darkened room in the morning; we were okay, but I can imagine some people might have an issue in summer. Also the walls are not very soundproof, so if you have kids that you want to get off to sleep you need to keep pretty quiet. Noise can also come in from the rest of the house adjoining one end of the apartment, though to be fair there was very little noise from the rest of the house so it wasn't a problem at all in practice while we were there - certainly there was no noise at night or early morning to disturb sleep.
