Alex is very responsive even during the wee hours of the night. He is also very accommodating and flexible in our requests.
The neighbourhood may get a little noisy at night because it is right smack within Korean town w lots of restaurants but overall acceptable.
There is a big Donki nearby which is very useful. We get our groceries and fav Japanese snacks/drinks there, and do not need to walk very far back to the accommodation.
Many eateries around (Korean and local alike) - no lack of choices . Family Mart and Lawson are at almost every corner of the street.
The apartment can accommodate at least 6-7 pax as there are 3 comfortable double beds and a sofa bed. We had 4 pax and it was good. The bathroom and toilets are separated so no need to fight for usage.
Overall we enjoyed our stay!
