Hotel the Castle Jamsil

Exceptional hospitality, great amenities, and a lifesaver for festival-goers!

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!

Great hotel near Lotte World Tower. I highly recommend going there for the Aqua Garden Cafe and the Seoul Sky observatory. I booked the "One Bedroom Suite" on Booking and got placed on floor 8. Do note that the hotel has two entrances, one for #1 and #2 and they lead to different buildings, so pick the correct one. There is free cereal, instant noodles, milkbread, cupcakes and drinks (mainly water and korean sprite) on the 17th floor. I included a pic of the view from the window there.

I absolutely loved the spaciousness of the hotel room (incl bathroom), and it was really relaxing to take a bath. There is a mini fridge in the closet (easy to miss, initially I thought there wasn't one). Do note that if you want your room cleaned during your stay, you need to give notice of this at the lobby. I conclude it's an amazing choice for a couple nights. For longterm do note the 14 min walk to Jamsil metro station as well.

The shittiest hotel I’ve ever been to in my life and I travel around the world quite frequently. From the moment we came the staff were so rude and unhelpful, the rooms smell really bad and are dirty. Very unwelcoming and had a terrible stay. Ruined my Korea experience as everyone else in the city is so nice. AVOID AT ALL COST.

Generally fine ,basic amenities. Bathrobe and towels were yellowish didn't dare to use it. Breakfast was basic toast , coffee machine , cup noodles and cereal. It's okay for the price but if want comfort it's not it. Bed was average too. Location is not bad though many food around and its quite near jamsil subway Station. But it's noisy till late night with people shouting and talking downstairs because there are so many bars and karaoke places around.

Cons
1. I dont link Resroom, Shower spread out all around to make whole get wet
2. Nearby hotel have many ppl smoking

The location and the service are excellent, however, the room feels quite outdated and is in need of general renovation. Parts of the wallpaper are peeling off, and it seems that the bathroom exhaust fan does not work properly. After showering, moisture does not dry well, which has resulted in some rusty areas.

I stayed on the 12th floor of the Hotel the Castle #1, but unfortunately, I had difficulty sleeping due to loud music coming from nearby commercial buildings. The noise, especially the music, continued late into the night and even into the early morning hours.

On a positive note, the cafeteria on the 17th floor is very nice. I particularly appreciated the 맥반석 (stone-baked) eggs served in the morning, and the fact that water is provided free of charge. However, the cafeteria is only open from 7 a.m. to midnight, which was disappointing. It would be much more convenient if it were open 24 hours a day, especially for guests affected by nighttime noise.

Due to the constant noise from the surrounding area, particularly the music that continues throughout the night, I do not think I would choose to stay here again.
