I had the best sleep in July at this hostel. That's probably because of the air conditioning (AC) and that my apartment doesn't have AC!
I booked a single room. I was pleasantly surprised that it came with a blow dryer, a refrigerator and a television. The room was quite small by Western standards. You need to fix the tv remote because it only stayed on one channel, 19. The common room is great to meet other people.
It was nice that our room had a kitchenette and a front loading washing machine. However, I noticed that it was still wet when I opened the door of the front loading washing machine. When a guest checks out, the staff needs to make sure the door of the washing machine is left open so it can air out and mold won't form. Also, the staff needs to clean out the detergent bin and drain the washer so that it doesn't overflow.
The first time I booked at this hostel, it was in July. Each of the bunk beds had its own lamp which is really nice when you want to read a book or tablet. The room had air conditioning which was really nice for the summer! The owner cooked pancakes for breakfast which was really nice. Unfortunately, if you have serious mobility issues (example: a wheel chair), you probably want to look elsewhere because there is no elevator in this hostel. Otherwise, it's a really nice hostel!
In this case, you get what you pay for. This hostel was basically a building with a lot of studio-type apartments. The room had a TV, a single bed, two bunk beds and a reading lamp. NO wifi. Across the street from this building was a free shuttle service to the airport. While walking around the area, I found a great seafood restaurant with a New Zealand theme. The food and the chat with the restaurant owner was the highlight of my trip!
It was quite busy, but not fully booked. Jin's Paradise is split into two floors (the 6th and the 7th floor) and there is one bathroom per floor. Quite a few people on the 7th floor either had to wait to use the bathroom or go to the sixth floor to use the bathroom. They provide a warm blanket for each bed, but I would still bring warm pajamas. Jin is a friendly and fun guy.
This hostel has lockers and they provide the keys for them. The kitchen is quite spacious for a hostel. There is only one bathroom and there are closed stalls for the two toilets and the three showers. That means both men and women have to share the bathroom. If you are one of those who must have their own men-only or women-only bathroom, this is NOT the hostel for you.
On the plus side, their women's dormitory room had the cleanest, nicest and the most spacious bathroom I had ever seen for a hostel! The staff helped me confirm my reservation on the JR Beetle (hydrofoil). On the downside: The directions from Hakata Station to the hostel go wrong when you get to the intersection because the intersection is not a nice 90 degree four-way interesection. It took me a while to find the place.
The owner has a cute kitten, Koom. Since exit #7 of Yaksu Station is closed off until April 2014, use exit #6. After going out exit #6, turn to the back and go straight until you see the IBK Building and the MiniStop. At the IBK Building, turn left. You will see a pharmacy on your left and Agit Guesthouse will be on the left of the pharmacy.
For a hostel your size, you really need a few more bathrooms. If you don't have the space for another full bath (shower, toilet and sink), at least have a half bath (toilet and sink). If you need to go to the loo often or have to have your own bath, then this is not the hostel for you! The staff was very nice. Your hostel is in a good location. I didn't realize that there is a calmer side to Hongdae!
Originally, I chose this guesthouse cuz Stay Korea was booked solid. The only downside of Seoulwise is that the ladder for their bunk beds are a little small and I'm a small person. Nevertheless, if I have a chance, I'll stay at Seoulwise Guesthouse!
