Hyesook is the friendliest, most accommodating host we've met. We really enjoyed staying in her apartment. It's in a nice historic building, but the bathroom is very modern and the kitchen looks new. Double windows (not double pane, but double windows) and shutters block out city noise and light if needed.
A quick easy walk from the main train station. It's possible to get from the airport to the apartment via train in under 20 minutes.
Coop supermarket is less than a minute away.
