English isn't my native tounge, so if we're talking international accents here, then I'd have to pick between the different international accents there is to Swedish. And if that's the case, then I pick: none.
You see, Swedish is a rather difficult language to learn (according to most foreigners and immigrants I've spoken to about it), and if you speak it with a heavy accent it's very easy to sound a little... "dumb".
I don't mean it in any superior kind of way, it's just that the language doesn't seem to carry well for some reason if spoken with too much of an accent (english seem to be a lot closer linguistically to many other languages, so I think it sounds a lot better even when spoken with an international accent).
Also, im not the kind of person who'd assume that someone is "dumb" just because they can't speak Swedish very well. But suffice to say that if it sounds "dumb", then it's not very likely that I'd feel that it sounds "attractive".
If were talking regional accents however, I guess there are a few that can sound a little "cute" coming from the right person. In fact, the accent I have myself would probably be the one I consider to be least attractive (apart from the one they speak in the most southern region of Sweden called "skåne", because that's just awful

). My regional accent (the one used predominantly around and inside the main capital), sounds incredibly "cocky" and hostile for some reason. There's no humility to it, it's like the very accent says "I'm better than all of you, despite the fact that I can't come up with any tangible reason for thinking that I am". Quite obnoxious to say the least.
If the choice pretty much bottles down to english accents however, then it's a bit more tricky. I guess it's because im more into the sound of a womans voice than her accent when I think of "attractiveness". Although I guess I could admit that a female voice on the more dark and husky side speaking in oxford english can sound terribly "naughty" to me.
