I hit my head going up the stairs, but that was sorta my fault, I'm 6'1". The location is a little sketchy...tucked in a very narrow street, that is VERY untouristy. Their map is pretty good, just keep peering down the alleys until you see the City Lights building, then walk confidently into the alley! Lots of rancorous small businesses selling everything from cell phones, to house goods to live eels (which they'll happily BBQ for you right there).
After spending a few days in Itaewon, I wanted a more Korean neighborhood experience, so I found Hotel Tong Vivace in the Dongdaemun district. I paid about $68 for a single room. This is more like a guesthouse, with minimal services. The staff was very nice and spoke enough English to make life easy. They will give you a combination to open the front door (the front desk isn't always attended after 6pm), and a combination for your room. Room was simple, clean and safe. I appreciated the room A/C and really solid wifi. I liked the Korean hustle and bustle and felt completely safe, even in the narrow streets. I don't speak Korean, but managed to get what I wanted when I needed it. So, I recommend this for anyone looking to live amongst working Seoul residents, away from tourists and foreign travelers. Very close to the fantastic Seoul Subway!
