If you are here to sightsee and literally just need a place to sleep this is everything you need and more. The Staff is amazing and the rooms have the necessities
The room was rather Spartan and the bed quite narrow... it wasn't much of an issue for me as I am rather thin (66 kilos), but if you are a big guy, it might be not be very convenient. But I give it 4 stars overall for price and convenience. Staying in an individual room + bathroom in a city like Seoul for 25 USD/night is really cool, and as they say "you get what you pay for", so for me, there is nothing to complain about. I was too busy exploring the city to care about my room anyway. ;)
This is an average guesthouse and for the price we paid, we'd have extended it if we weren't at the end of our Korea trip. There was a sale so the double room with private bathroom that we stayed at was worth it. The thing I didn't like was that it was hard to find, and you had to go into two alleys. We went down the wrong alley and got lost. They only posted a sign to the guesthouse from one direction but we came in through another street and didn't see anything. The best part was it's an amazing restaurant area, lots of good eateries just right outside those alleys and we'd have loved to explore the food in that area more. Some hotels we stayed at in Korea wasn't by that many restaurants with such huge choices. It also had AC in our room and that was nice because the window was really small and the room not very large so it would have gotten stuffy otherwise.
