Hongdae is the place to stay in Seoul if you want a direct airport train and a late night out. Skip it if you go to bed early. This page covers Hongdae only. If you are still choosing between districts, the cards below lead to the area guide and the comparison.

The airport train is the main reason to stay here

Station: Hongik University Station is on Line 2, the AREX all-stop train and the Gyeongui-Jungang line (AREX website, opened 11 Oct 2026)

Price: AREX all-stop by transit card: ₩4,650 from Hongik University to Terminal 1 and ₩5,250 to Terminal 2. Seoul Station to Hongik is ₩1,550. A single-use card adds ₩100 and a ₩500 deposit that you get back (AREX website, opened 11 Oct 2026)

Time: Seoul Station to Terminal 1 takes 59 minutes and to Terminal 2 66 minutes. Some trains add two to six minutes (AREX website, opened 11 Oct 2026)

On the AREX line the stops run Seoul Station, Gongdeok, Hongik University. So Hongik is two stops closer to the airport, and the ride is shorter than 59 minutes. We did not find a Hongik time on the AREX pages. Our older guide says about 55 minutes. We have not re-checked that figure.

The all-stop train is the cheap choice. The express train skips Hongdae, so you cannot use it to get here.

Airport bus 6002 and the night bus

Bus 6002: Fare ₩17,000. From Terminal 1 the first bus is 05:44 and the last 23:29. The stop is No. 6 on the first floor at Terminal 1 and No. 30 on level B1 at Terminal 2. Its stops include Hapjeong Station, Seogyo-dong (RYSE Hotel), Hongik University Station, Sinchon and Ewha Womans University Station (Incheon Airport bus page, opened 11 Oct 2026)

Night bus N6002: The airport page lists six departures from Terminal 1 between midnight and 04:40. Stops: Hongik University Station, Gwanghwamun, Dongdaemun Station and Cheongnyangni Station. The airport page says ₩17,000. The operator's fare page says ₩10,000 for a night bus. We could not tell which is current (Incheon Airport and Airport Limousine websites, opened 11 Oct 2026)

The payment rules from our Myeongdong page apply here too. Pay with cash or a T-money card, since the bus does not take credit cards. At Terminal 2 you buy a ticket first.

Note: The first-bus time of 05:44 comes from the 6002 summary. The timetable table on the same page starts at 05:34. Treat the first bus as about 05:35

Hotels we could check

Mercure Ambassador Seoul Hongdae: 144 Yanghwa-ro, Mapo-gu. The hotel's page on the Accor website lists Hongik University Station at 100 metres and a one-minute walk. The page gives no exit number (Accor website, opened 11 Oct 2026)

RYSE, Autograph Collection: Bus 6002 has a stop named for it, "Seogyo-dong, RYSE Hotel", before Hongik University Station. We could not open the hotel's own page, so we have no exit or walking time (Incheon Airport bus page, opened 11 Oct 2026)

That is the whole list we can stand behind. Our own property list has 34 Hongdae entries, mostly guesthouses and hostels, taken from OpenStreetMap with a name and map point only. Hostel names live on our hostels page, so we do not repeat them here.

Which side of the station, and what we could not confirm

We could not open a Seoul Metro page for Hongik University Station. So we cannot give a checked exit list.

Note: Unconfirmed lead: two travel sites (ivisitkorea.com and Lonely Planet) say Exit 9 leads to the main shopping street and Exit 3 leads to the Gyeongui Line Forest Park and Yeonnam-dong. We have not checked this against Seoul Metro. Seen 11 Oct 2026

If that lead is right, a hotel near Exit 9 is on the busy side and a hotel near Exit 3 is on the Yeonnam side. We found no hotel page that says which exit it uses, so we do not name a hotel for either side.

Yeonnam and Sinchon

Yeonnam-dong is the Gyeongui Line Forest Park side in the unconfirmed lead above. Sinchon is a stop on bus 6002. We found no official page for a hotel in either place, so we do not name one. If you book in Sinchon, bus 6002 stops at "Sinchon Hyundai Department Store" and "Sinchon Station".

Noise and hills

Note: Our area data (checked 1 Oct 2026) says Hongdae is "noisy well past midnight" and is further from the palaces. Our earlier comparison guide says the main street runs until about 4 a.m. on Fridays and Saturdays

Note: We found no official source on slopes or on the noise of a single street. Do not treat any street as quiet until the hotel confirms the room faces away from the road

What a night costs

Price: ₩80,000 to ₩160,000 for design hotels and guesthouses. Hostel beds below ₩30,000. This is our band, set on 9 October 2026. It is an estimate, not a quote, and we did not check live rates

Who Hongdae suits, and who should skip it

It suits people who land late with bags, want a direct train, like live music and late food, or are on a budget. Skip it if you want quiet evenings, if your plans are mostly the palaces, or if your hotel is above a bar street. In that case, look at the budget guide or a quieter district.

What is checked here and what is not

Checked on 11 October 2026: the AREX fares, train times and the lines at Hongik University Station (AREX website). The bus 6002 and N6002 fares, first and last times, stop numbers and stop lists (Incheon Airport bus page). Mercure Ambassador Seoul Hongdae's distance to the station (Accor website).

Not checked: any exit number for a hotel, which exit faces the main street, Seoul Metro's own exit and lift list (its site did not open), the Hongik-to-Terminal-1 train time, the night bus fare conflict, RYSE and L7 Hongdae on their own pages (blocked), street noise, slopes, and live room rates. We did not use forum posts. Reddit blocked us, and a PTT search returned no posts. We did not read Naver.
