Yeppers. Of all the cities that I've ever been to, Dublin is a pit. And yet I'm here several times a year. If it weren't for friends and family I wouldn't bother. Oh yeah, these people are truly loved! Good thing Dublin is easy to get around. From the Airport to the City Center takes about an hour. I usually take the 16a or 41 bus. It's only 2.20 euro. You can take the 747/748 but it's 6 euro. Call me cheap. Both busses drop you off on O'Connell Street - near the giant useless stainless steel spire or needle. Not sure the point of that thing.
I stay at Abigails Hostel. It's on Lower Ormand Quay. If you get off the bus and walk toward the river, hang a right after you cross the river, Abigails is about 100 yards up. It's a great hostel. The staff are friendly. The rooms are functional. Beds are sleepable. EXCELLENT shower pressure and plenty of hot water. I've either stayed in a 8 or 10 bed en suite (the toilet and shower are in the room). I've NEVER had a problem. They do have a free breakfast. It's the usual Euro fare. Enough to fill you up and get your day started.
The internet there is way freaking pricey: A euro for 15 mintues. Really??? There are still plenty of places in London where a pound will get you an entire hour! That's the thing you have to watch out for in Dublin - it can be hella expensive. Weird that. I shop in the grocery for brekkie bread and caffeine. No decent tea or coffee places that I've found.
Definitely treat yourself to a late night at Supermacs!!!! It's a dive burger joint on O'Connell. They serve more than just burgers, but I always get a cheeseburger and chips. It's a great late night place to gather with your mates and eat and shoot the shite. It's a very low brow McDonalds. There is a McDonalds open 24 hours down the street - closer to the Liffe. But SUPERMACS is the better option. Cheaper prices. Better food. More fun!
