There's a coffee shop/cafe on site. Free breakfast is served daily. WiFi is free in public spaces. KOZAYO Hongdae Hostel also features a rooftop terrace, laundry facilities, and a front-desk safe.
Smoking is allowed in designated areas at this 3-star Seoul guesthouse.
The placement of the hostel is the best. Everyone is respectful and quiet. Also as a woman it made me feel very safe because there is a QR code required to go in the elevator and in the sleeping area.
