Natalie is a wonderful host! Communication was very smooth and she was always reachable via message even when not around. Lovely touches as tea/coffee, bottled water, and the possibility of borrowing local public transport card (I had my own but thought it was a nice touch for visitors!).
Her house is very stylish, and is located in a quiet and pretty street in K-Town. The neighborhood felt very safe (despite what you might have heard about the area), I walked and used public transport and felt perfectly fine.
My flight back was leaving in the evening and she gave me the possibility of a late check out too, which was really nice of her.
I would definitely recommend Natalie's place and I'd stay at hers again :)
