@Friendshipgroup , it will be fine, but a lot of nerve holding and financial back up is needed. OP, you may want to factor this in.
Year 2:
Many Halls students ended up in the Point student accommodation with people they met in Halls (mostly non- Dublin Irish; there weren't many UK students there). Luas is very near by, but it's not, in my opinion, a great area for students: mostly businesses so streets are quite lonely at night, although usually someone to come home with. The full annual fee has to be paid upfront (!) but I have heard that you can get out of it as long as you find an acceptable replacement. Booking for 2025/6 is not open yet. The US students seem to stay at Kavanagh (which they irritatingly mis-spell, and mispronounce no doubt, ' Kavanaugh- Kav-an-aw'), Cork Street or other D7 and D8 student accommodation, which is more intercollegiate and mixed years than Halls which are Freshers only. Quite similar to say London Uni set ups.
For private accommodation, best to keep an eye on the market, but there isn't really a student house churn like here, so places aren't available pre-Christmas for 2025, like at several UK Unis. In reality, expect to start looking properly April or so, move very quickly, and to pay annualised rent (inc over the summer). Many landlords will expect full year's payment upfront unless you have an Irish guarantor.
As with the UK, friendships and preferences flux, so committing to Year 2 arrangements early is a folly methinks.
Year 3: If very lucky, because they barely award any, Schols (sat in 2nd year) comes with an on-campus room (possibly a set, and crusty!). 60 ish places out of 3000 U/Gs. Some do Erasmus, so are away all year or for 1 of the 2 semesters, so there are regular calls to offer or request. I've read that some students see Erasmus as a way of avoiding the 3rd year accommodation problems as well as a nice year away.
Year 4: Notionally prioritised for on-campus rooms, but again not enough to go around, and offered so late that you'll have already booked and paid for the alternative. But we'll be hoping for this!
I'm sure your daughter will work it all out, whilst we pedal like mad in the background making it all work! I hope she's enjoying herself, sounds like they have great weather at the moment. Suggest she gets out to Howth, Malahide, Dalkey, Sandycove or Bray on the Dart, or Bull Island (bus) while it holds fine, so she can better appreciate the wider area. Also suggest she watches out for the Race trips and other social events, that book out quickly. I hope she has a fabulous time.
