It's actually a hostel. It's simple & doesn't have as many facilities as hotel such as there is no elevator (but staff will help to take your luggage up & down) no everyday room cleaning service (but you can request every 3-day stay), no electric kettle (but there is warm & cold water supply in the lobby area of each floor). But the location is excellent! It's at the centre of Gangnam, near subway station and thousands of restaurants, cafes & clubs nearby. Many of them are running 24-hours. It's just one thing that it would be noisy at night since that is an area of entertainment in Seoul. With the price, it's absolutely value for money!!!
We remarked we will arrived in the mid night, but when we arrived, door is closed and no one answer the phone call, luckily some guest come back and we can get in the the hotel.
