If you are attending a wedding at the Trump Hotel, or just need a place to stay in Doonbeg, you can't go wrong by booking a room at Sinead's. Our room was very spacious and private, with our own bathroom and a key to lock the door as well. The bed was SO comfy and the comforter was even better. Sinead replies instantly to every message you send her, so checking in was a breeze. If we are ever back in Doonbeg, we would happily stay here again.
PS - If you are attending a wedding at the Trump Hotel - it's not even a 5 minute drive away. You could probably even walk if you wanted to!
