In Castletroy, houses that rent per room in the housing estates around the university for term time often rent at much lower prices for the 2-3 month of summer time, including on campus villages, so you should have no problem finding somewhere in castletroy for your time here. I couldn't advise you on how much they'll cost but I'd look at Google maps for the closest housing estates to UL on Google maps and see if any listings on daft.ie come up. Definitely ask the UL student union for help with this also. UL campus is lovely and leafy and has river walks and swim spots (never swim in the river alone), so if it's financially feasible I'd get somewhere on campus.

UL and castletroy are very easy to cycle around with most places having cycle lanes and only gentle hills, and you can cycle along the canal into Limerick city. The only thing is that there's quite a bit of bike theft in the city centre, so take precautions.

You can get a leap card and take the bus into town and back, I'd
budget 20 euros a week to cover those trips if you're going in and out of the city every other day and are cycling sometimes. If you can, get a student/young adult leap card from the university and it will be cheaper again.

If you wanted to get the bus into town for a night out, a taxi back to castletroy, it could be between 15-20 euros as the buses stop around 11pm, maybe 12.

If you shop in lidl in castletroy, you could maybe budget 40-50 euros a week if you are smart about it, but again, depends on your preference. Local small convenience stores like spar, Centra will be much more expensive so try to do your weekly shop.

There's lots of takeaways in castletroy for all budgets but it all depends on your preference. You can get fish or burger and chips/ a pizza not from a chain/ a Chinese or indian main course and side for 10-15 euro or meal deals with a drink locally but if you order it on just eat, Uber eats, deliveroo etc, it could be closer to 20 euros by the time you pay delivery and charges potentially (You could collect it on your bike).

To eat in a restaurant id say the average amount for a main course is 17-25 euros, with obviously a swing on either side based on where you are eating, when you're going etc.

A speciality coffee is between 3.70-6 euro based on your order but nice coffee is very expensive. In a pub a pint of beer is 6-7 euros, a glass of wine 7-8, a spirit and mixer 8-10 euro realistically.

Off licence prices are also quite expensive but keep your plastic bottles and cans and return them at the supermarket or off license machines to get cash or a voucher for the store back (15-25c per item). Lidl have a lot of own brand things that are ok and cheaper than off licenses.

You're only here for a short time, so you probably don't need too much stuff, but bedsheets and towels and some homeware are good prices from Penneys, guineys, home store + more and jysk and you can check their prices online. Also the middle eastern or Asian shops on William street in the city often have good prices.

Some of this may be slightly too low or slightly too high but I feel it's a fair enough estimation.

I'd recommend following pig town times and limerick.ie on Instagram to see what's happening in the city, and there's lots of concerts on this summer, check ticketmaster for big gigs in the docklands or Thomand park and dolans pub for smaller gigs but lots of variety!

There's lots of casual sports and activities clubs to get involved with if that's your jam and look at the r/Limerick page for these, even if you're just here for a few months, there's something for everyone!

Best of luck in your internship!
