It's Friday night, so if you want to come and party, one of my neighbors has a party that's in full-tilt now. Just take the green line out to Vällingby once you arrive in central Stockholm. Walk about seven minutes from the station and look for the P-A-R-T-Y. I'm sure they won't mind if you crash, it seems like half the city is already there.
How do I know? They just woke me up from my nap. And it stinks of cigarette smoke in here from the stairway.
1 AM addition: The party seemed to die out around midnight, but it will linger on thanks to the person who puked in the snow just outside the front door.
