We stayed at AC Hotel by Marriott Seoul Geumjeong for 6 nights (Apr 1-7) as a family trip from Sydney, Australia. Overall it was a decent stay, though with a few notable issues worth mentioning.
On the positive side, the hotel was absolutely sparkly clean throughout - rooms, corridors, and common areas were immaculate. The staff were very polite, warm, and welcoming at every interaction, which made a real difference. Breakfast was enjoyable and of good quality, but unfortunately the exact same menu was repeated every single day with no variation, which became monotonous by the end of a 6-night stay.
However, we did experience some disappointments. We booked a Premier King Room with City View, but the view was largely blocked by a construction site directly in front of the window - they changed our room in the second day of stay. We were also misled about pool access, which was a letdown especially travelling with kids. Additionally, there was an unpleasant odour in the room that we had to deal with(was fixed after our complain to service desk). We raised these concerns with the hotel and Trip.com, and while the support team was responsive, the outcome didn't fully address our losses.
The location near Geumjeong Station was convenient for getting around Seoul.
