Cost is all relative, I guess. Pay is lower than SF, but I also am paying less than half of what I would for my apartment. Given that I was spending a lot of money to take what vacation I could in Europe anyway I actually save a good deal on vacation budget this way too.
I find I have to be careful in conversations because I sometimes gasp at how cheap places are, perhaps insensitively. I guess I just got used to apartments always being $2000+. Of course, it still stings that a "cheap" pint is €5 (I remember two dollar beer night in college not so many years ago!)
I'm not sure what $500 per month you refer to, but I'm guessing transportation costs. I have generally preferred living in places that didn't require owning a car, and find it makes a huge difference. I was in Berkeley for a while, and Santa Monica after that. Note that in Santa Monica I found it necessary to share a car with the gf; You can get around SM fine with a bicycle but LA remains a desolate suburban hellscape.
Also, while it is certainly possible to live in SF without a car, it's even easier in Dublin, which saves money as well.
And again, I'm just a sucker for Europe. I was spending $2 grand a year on plane tickets to get over here, and now it's an €80 (or so) flight away.
1270USD is about 950 euro; at a pinch, you can still get a city centre 1 bed for that, though a bit over 1000 would be more common. I'm also a bit suspicious of its restaurant costs; they seem high for Dublin, and its telecoms costs, while reasonable a few years ago, are now too high.
