It's conveniently located near the station and has many convenience stores, pharmacies, supermarkets, and restaurants.
The room is clean and the ondol (Korean heated floor) is nice and warm.
Shampoo, conditioner, body wash, and toothbrushes for two are provided.

Transportation is very convenient. I was able to get some work done well because it is located near subway stations on Lines 7 and 4.

I don't recommend it if you don't want to waste a lot of time just checking in.
The hotel is only connected by phone, you can't call from our e-sim cards. We called via the Internet, there were some problems with the sound, we couldn't hear the other person. As a result, we managed to go into the hotel and leave our suitcases.
In the evening, we came to get into the room, we called again - this time we couldn't get through at all. The girl who was cleaning the rooms helped us. She went up to the owner (who was in the hotel the whole time!) and got the code for our room from him.
Service 0/10.
The room itself was not bad, it was mostly clean, the shower was uncomfortable.

This hotel is located near Isu Station. It is conveniently located near the station, and although it is unmanned, it is easy to contact the person in charge. There are many places to eat nearby.

The interior was clean, and it was close to the station, so transportation was good. It was good except for the bedding management, which may have been a bit lacking due to guests using it roughly.

I couldn't find anyone at the hotel at all. I was told that I could go to the second floor to find him, but I couldn't find him even once... I even had to make a phone call to check in, which was very inconvenient for foreigners because I couldn't speak Korean and English. Communicate, and you should send a notification letter when the check-in date is approaching... As soon as you enter the hotel, it is very comfortable, but the pillows are too flat and the bed is too hard. The sheets do not feel like they have been heated or sunbaked. The bed is very damp, as if it does not look like it If it's dirty, it won't be washed... The supplies should be prepared at the door every day for those who stay longer, and they just happen to be brought to them during cleaning... There are no dishes to use, and the sink seems to be of no use.

It's nice because it's close to Isu Station. However, the soundproofing is not good, so you can hear the noise from outside. Other than that, everything else is good.

It's okay for families to come. The mattress wasn't comfortable.

It is close to the subway station and has many restaurants nearby, so the amenities are good.
The interior is neat and well cleaned, so I am very satisfied. However, I was confused because I did not receive a text message informing me of room admission, and when I spoke to the person in charge, there was a lack of detailed instructions.
