I guess most people who book a Hanok are aware but this is not a luxury stay. The room is small, as expected, your bedding are a thin tatami, hard pillow (strangely comfortable, I think there's buckwheat inside or something similar) and a blanket. There are plugs, ac unit, a TV, hairdryer and very small towels (in large quantity).
The room is bare but lovely.
The shower system, as it seems quite common thing there, is made up of a sink, inclined floor and a shower head, all in the same space with toilet next to it. It is clean but will surprise some people.
Unlike what most people said about Korean toilets, they seemed to be working quite well and you could throw paper in it.
Breakfast is prepared fresh at 8am sharp so oversleeping is not an option. It's a delicious vegetarian (probably even vegan) Bibimbap. There's also tea and coffee available.
Hosts are very helpful and welcoming and happy to help. English is spoken but limited although I did not have any issues understanding or being understood.
