Use Exit 1 from Jongno-3 Station and walk towards Tapgol Park. The guesthouse is on the 5th floor of a building which faces the park. The stairs that leads to the guesthouse is right beside a Starbucks. I was given a key code to the main entrance and another code to my room. I appreciated the privacy and the safety features provided. The palaces, quaint villages, cafes and restaurants are just walking distance away. Using the Naver app, it was easy to ride the metro and the public buses. There was also an airport bus stand within a 5 to 10 minute walk around the corner of the building.
