Liam's place is well situated in a residential area just near the Croke Stadium. There was no match during our visit, but I can imagine that it could be very crowded on matchdays - best way is probably to go to the match yourself then, I guess. It's a 30 minute walk to the main attractions such as Trinity College, St. Patrick's Cathedral etc. However, the bus connection is very goood and there are enough supermarkets/grocery stores in the surrounding blocks. Another plus is the proximity to the airport (just 20 minutes by car) so we didn't need to get through the crowded city to get there. We haven't been out at night so I can't say anything about safety, but my wife took a walk in the evening and wasn't that comfortable when she returned from the city to our appartement. However, that's just a subjective impression.
The place itself is very clean and we didn't miss anything in the equipment. The kitchen could need some more cutlery, though everything is there - but only three or four times. The backyard is completely sealed so we didn't spend any time there (it has potential for more), but it offers a good opportunity to hang and dry the clothes.
Everything considered, it met our expectations and offers great value for Dublin. I can recommend the place for everyone who wants to explore the city by him- or herself and who is okay with a minimalistic interieur without any details.
