And of course, in large part because this is effectively a bilingual country. In the years I've been here, I've only talked with a handful of native-born Swedes who did not speak English. Those were older people who had learned German as a student. (There are non-native-born Swedes, like immigrants from Chile who speak fluent Spanish and Swedish, whose English can be poor.)
So yes, it would be easy.
On the first evening I had a bit of difficulty operating the keycard outside the hotel. A chap came up to me and started talking, presumably explaining how to use it. "Murgle burgle burgle wurgle furgle", he said, or something like that. I must have looked blank for about 0.1 seconds before he slipped, with barely a beat, into flawless, unaccented English. And the first English words out of his mouth were, "Oh, sorry..." :)
(This was not a unique experience. Even the petrol station attendants spoke great English. You don't even get that in England.)
