Jacob's Inn was perfect for what we needed in Dublin - cheap and within walking distance to everything. We didn't have to use public transit at all but it was close to the central station. Super clean considering we stayed in a 10 person room. The pods the beds are in were great, way better than bunk bed hostels I've stayed at in the past. They had events (walking tours, pub crawls, etc) which is super nice to get to know the city.
