The hotel location was perfect as the Airport Shuttle Bus No. 6002 stops very near the hotel. It was also right next to Cheongnyangni Station where you can take the Seoul Metro virtually anywhere in the city.
There were lots of food stalls near the station where we were able to try local street food, a few restaurants for authentic Korean food (but without English menus so you'd have to be able to point at pictures or to what other diners are ordering). Of course, there was also a McDonalds nearby as well as Lotteria (a local version of McDonalds). There were also a few coffee shops and chicken and beer places nearby.
The rooms were comfortable, even if a little small. We asked for 2 non-smoking rooms next to each other which they were able to provide. There was free wifi which is kinda standard nowadays. The rooms were clean and the beds were perfect. They provided water, coffee and juice everyday. We also had free breakfast everyday which was much appreciated, even if the food was just basically rice, noodles, porridge, sausage, soup, salad and cereals everyday.
The only negative was that the shower didn't have curtains so the floor might get a little wet, and there was no place to hang towels or clothes which makes things a little complicated. The toilet was great though as the seat was heated and the bidet worked perfectly.
Overall, great location and nice hotel at a budget-friendly price. What more can you ask for?
