Hotel the Castle Jamsil#1

Perfectly accessible by subway or bus. The hotel is very easy to find. There are so many cafes and restaurants nearby, as well as two huge parks that are absolutely beautiful. Even though it was right in the middle of a busy district, the room was very quiet. The lounge area with free drinks on the top floor is a welcome bonus.

Not a huge deal but the hotel has a very strict check-in time so you won't be able to enter your room earlier. Thankfully, you can leave your luggage at the reception. Another minor thing is that there are no bedside lamps and the light switch is on the other end on the room from the bed.

Kind and friendly staff. Room was great with a big bathtub. Location is perfect

A lot of floor to ceiling mirrors in the room

I stayed here for four nights to attend the Seoul Jazz Festival at Olympic Park, and the location was absolutely perfect. It is within walking distance of the venue, meaning I could entirely avoid the massive post-festival transit crowds without needing the MRT. It’s also incredibly close to a CU convenience store and walking distance to Lotte World Mall. ​The room itself was very spacious. After a long day of standing and moving at the festival, being able to unwind in the solid, American Standard-sized bathtub was an absolute luxury. ​My personal favorite highlight was the 17F Coco Lounge. It’s a beautifully designed space where I could truly relax. I thoroughly enjoyed the complimentary snacks, especially the smoked eggs (just like the ones at a traditional Korean sauna!), the cheesecake, and the coffee. ​Most importantly, the staff’s hospitality is unmatched. I accidentally left my bag at the hotel after checking out. Seonji Park and Gwanghoon went completely above and beyond by coordinating with me late at night, hailing a taxi, and ensuring my bag was delivered safely to my next hotel in Myeongdong. I am incredibly grateful for their timely, professional, and stress-free support!

There is nothing to complain about, just a few minor things to note for future guests and management: (1) Vegetarian Snack Options: As a vegetarian, I noticed the Coco Lounge didn't have any vegetarian-friendly cup noodles. The only non-meat option was the Nurungji (scorched rice cup), which tastes a bit like plain, soggy cereal soaked in hot water—great for a sensitive stomach, but not quite satisfying after a late-night festival! It would be amazing if the hotel could stock at least one vegetarian/vegan instant noodle option in the lounge. (2) The Bed: The mattress is on the firmer side. I understand this is a common preference in Korea, though personally, I prefer a slightly softer bed. (3) AC & Light Controls: The air conditioning control is a bit confusing. It runs through the TV remote control rather than a standard wall unit. While this is noted on the check-in information sheet, I didn't notice until I called the reception. I highly recommend placing a small English/Korean sticker next to the wall panel explicitly directing guests to use the TV remote for the AC. (4) The "Master Off" Button: Pressing the "turn off all lights" button on the remote turns off the lights but activates a very bright backlight on the wall controller panel. I had to get out of bed in the middle of the night to turn off the wall panel manually. A true "one-click" blackout option would make the stay flawless. Overall, I had a fantastic stay. I will definitely choose this hotel again next time I'm in Jamsil and highly recommend it to anyone visiting the area!

It was close to a lot of restaurants and subway stations. The cafeteria was great for the nights I didn’t want to leave the hotel for food or for a quick bite before sightseeing.

I wasn’t able to control the room temperature.
