Fine for solo traveller. My sister was here 4 days alone before I met up with her. She felt safe using the train just down the street and walking in the surrounding neighbourhood during the day. You take the airport bus to konkuk university. Must listen carefully for announcements. Also, before boarding maybe google translate and pass a note to the driver that you want to be informed when to get off there. Then you take a taxi or at konkuk university there is a train station and you'd take it to seongsu station which is only 1 stop over from konkuk. Then exit at exit 3 at seongsu station. If using a taxi from konkuk, you can google translate the address for the driver as I did. Konkuk has some restaurants and also the grocery store has a large dining area with various choices and inexpensive. We had pizza one day and pad Thai another day. Also, Coex mall in gangnam is a 10 minute ride from seongsu and they have many reataurant options and an aquarium and movie theatres too. There is a bakery across from the hotel called tous les jours where you can get pastries for $1-3 each. Have a safe trip.
