This pension has a great view as it is rght on the East Sea coastal road. The owner, I assume, was friendly and communication was easy.
The room was spacious and clean, equipped with a kitchenette (minus a stove). The rooms on each floor do not share walls, so it's quiet. You don't have worry about hearing or disturbing your neighbors.
There is a convenience store next door. Small restaurants are a 10-15 minute walk away. Although, as a solo traveler, Korean style group meals aren't a real option.
Beaches are within an easy walk. Bus stops are a 10-18 minute walk.
