1. The room as described. But you have to think twice are you ok with tiny room - there are a bed, a drawer unit and you standing between them. That's all. You can put your suitcase on top of the drawer unit.
2. I was unpleasantly suprised by neighborhood where the house is located. My local friend and taxi driver told me that I should be careful and don't wandering around. Some buildings in this area are surrounded by barbed wire. Fortunately I didn't have any problems there, but I think you should know about it. A taxi from the centre of Dublin costs 7 euro.
3. You can use washing machine twice a week - on Saturday and Wednesday (not sure about Wednesday). You need 2 euro coin to use the washing machine and dryer.
4. The hot water was just in the shower. I expected hot water in sinks in the bathroom and in the kitchen as well. Maybe it was my fault and I didn't figure out how to turn it on. But unlikely I couldn't turn it on in both sinks. If it is true and the hot water only in the shower, it should be mentioned in the description.
