Homestay (Mangpo station pick up) Korean reservation is not possible

My apartment is new. Everything is clean and neat. It has a security system so it is safe. When you text me or call me, I will pick you up. I have a 4 year old son. He makes some noise but his room and the guest room are far away. A lof of Kyunghee university students have asked how far it is from my house. I checked my navigation it said 2.8 km. There are buses but better to ride a bike. A guest can borrow a bike or I can give a ride cause it is on my way to drop my baby around 9 am The space There are a big shopping mall called Emart traders and Mangpo station Other things to note If you lose a sensor key, you should pay for it.
