Hotelette is very close to exit no.10 of Seoul Station, which is why I chose it in the first place. The room is a bit tiny, as expected, but very neat. Had everything I needed. The staff was very nice and helpful. The manager lady helped me move my luggage to my room when I checked in.
However, you have to tell the staff if you want room-keeping service. But then you get what you pay for. So I'm okay with that.
Overall, I'm satisfied with my stay in Hotelette.
