I recently stayed here with my wife and a friend. We had a small issue where there was a date conflict on another booking site for the hanok, so our stay was shortened and we got a refund.
Although it would be easy to complain about that.... the place was really nice and we had a great time.
Location: right in Bukchon Hanok Village. Lots of cute cafes and stores, and a great place to walk around. There's a mart close by if you need random goods. The downside is that it's a little further from a metro (maybe 10 minutes walk).
Check in: aside from being a little hard to find the first time, check-in was very smooth. The door has a code so you can just show up at your leisure and get settled.
Place itself: it's hard to have a nice balance between the historic style of a hanok and modern comforts we expect, and I think this place had a wonderful balance. Room ACs keep things comfortable in the summer. The decoration is very tasteful and beautiful. A very "instagramable" backdrop, if that's what you are in to.
The bedrooms and bathrooms are a bit small by western standards, but if you don't want a traditional floorplan, don't stay in a hanok.
Amenities: not many Korean homes have a dishwasher or a clothes drier: this place has both! very convenient when you're travelling. Also, while a "foot spa" might sound a little silly, after walking around Seoul for many hours, it is amazing!
I would definitely recommend this place for anyone who wants to be in Bukchon, and would be happy to come back again in the future!
