Phelim is a very helpful and conscientious host and communication was great with him.
The apartment is conveniently located near the Heuston Station (7 minute walk), so you can hop off the 747 airlink terminal without having to switch buses when arriving from or going to the airport. Buses 13, 40, and 123 have stops located nearby (5 minute walk) that take you to Dame Street and Temple Bar area. Location is very convenient if you are taking the bus, but it is a bit of a walk to the city centre (20-25 mins on foot) so I would recommend getting a travel card if you are staying here. The three day travel card is excellent value if you are taking the airlink because it only costs 19.50 and a return ticket on the airlink 747 already costs 14 in and of itself. There aren't a lot of shops or eateries in the immediate vicinity except for the Guinness Storehouse, so you are going to have to go the the centre to eat out but it isn't that far. The bedroom was clean and kept well and Phelim provided us with fresh, clean towels. The only issues, if we are to be picky, is that the water pressure is not very high, and it takes a while for the water to load for the toilet flush and that there was not a lot of reception on our cell phones at the apartment (with 3 as carrier) and unfortunately WiFi was down while we were visiting (Phelim is having it repaired). All in all, very good value. We would stay here again if we were to be back in Dublin.
