Last friday we holded a party on our rooftop. It is on the 15th floor, one of us had to go there by the stairs to allow the others to take the elevator... but it really worth it: the view was great. And the mood of the party was perfect.
We used bottle of soju and smartphones to get lights. Then around 11 one of our housemates bring some candles.
It was really hot, but there was some wind to keep it barable. We enjoyed some juice, soju, beer, chicken and pizza.
