CMy husband and I stayed at Hongdae Guest House for two nights, and had a lovely experience. The photos don't do the place justice: it is extremely clean, with lots of natural light in the morning from big windows. The location is also great. It's quite close to Mapo-Gu Office metro station, and walking distance from the Hongdae shopping area. It's a great deal, and we recommend it highly! Hong Chulki is an extremely accommodating host. He was able to give us a place to stay at the last minute, and was very gracious when it took us four hours longer than expected to arrive.
