This thread isn’t saying that Dublin is a shithole. Dublin is a small city (at least its city centre is very very small) and I’m just pointing out some things which I have noticed, even if they are trivial.
Things are slowly improving, but I think they’re too slow. The population is increasing very fast, and it doesn’t look like the city can handle it. Until another 15-20 years at least, it will be difficult to live in this city (or town).
