It's a good place if you only need a place to sleep so for backpackers and young people I believe it's great. However, compared to love motels I wouldn't call it 'comfortable' (I lived and worked in Korea for a few years when I was younger and stayed at many love motels, I also lived in a tiny office-tel for my first job); I stayed in a single room and I only slept well when I was drunk (as the bed was very uncomfortable and hard). The room also wasn't that well ventilated but it was quiet (which is remarkable considering the location).
I wouldn't recommend this place if you have loads of luggage or are a couple/have children (I travel light).
The room does however have good wi-fi, a TV, air-conditioning and an adequate bathroom (but no separate shower space, this however isn't unusual in north-east Asian hotel rooms from my experience). There's also free toast and coffee from 8am-10am (or there's Holly's Coffee, Subway, Burger King, KFC, McDonald's, Taco Bell and lots of other places downstairs along with a GS25 convenience store). It's also very close to Jonggak (exit 12 is very close) and Jongno 3 ga subway stations on line 1. The 6002 bus from Incheon Airport also stops nearby. The Nami Island tour bus and Seoul tourist bus stop are also close.
Overall, like I say it's a good place for budget or younger travellers (or if you're teaching English in the Korean countryside, it's a good place to just sleep on Friday/Saturday nights).
