Jens is a cool and helpful guy, and speaks English fluently (like most people in Denmark). His flat is awsome, has everything you might need, and just 1 min walk from the metro station, shops and pubs. City centre is about 10-15 min by walk or 5 min, with bus/metro, but you should really walk becasue public transport is very expensive, however Copenhagen is beautiful. Anyways, Jens place is a perfect spot, to stay in Copenhagen.
