I spent two nights staying at Maureen's house and can recommend it as a very good value, well located place to stay. The room is very large, and the bed comfortable. It was also very clean.
The house is in an affluent, safe area of Dublin, and is within a few minutes walk of the Dart (train) station (providing quick access to the city centre), the beach, the RDS and the Aviva stadium. Maureen was always very quick to respond to messages, and the check-in was smooth (her sons, who stay in the house, were there to let me in and give the tour).
