We had a very good three night stay at Laura & Diego's place. The location puts you right in the heart of Temple Bar, so perfect if you're keen to experience Dublin's nightlife. We had no issues preparing for the trip or finding the apartment, which is perfectly comfortable and relatively sound proof for the area.
The hot water issue is interesting but I'm told that's standard for Dublin. Also, prepare for damp towels.
Overall, the stay was comfortable and fine. Thanks.
