The place is located about 8 minutes away from Shin Okubo station, but because of the crowds which tend to form especially around food stands, it tends to be 10-15 minutes away on foot.
The apartment is located in a building with restaurants and so you'll be able to smell the food (especially the smell of onions) as you exit the lift.
The interior of the room is exactly what you see in the pictures, with 4 double beds, a sofa and a kitchen. However, the cleanliness of the apartment remains much to be desired as we checked into the room with thick layers of dust beneath one of the beds. One of the mugs in the kitchen also had stains could still be seen. Some of the bed sheets also had a yellowish stain on the side as well.
As the building is right by the main road, we would sometimes also hear ambulance sirens past midnight, and it can be quite noisy at times due to trucks delivering goods to the restaurants nearby.
While the sounds from the external environment cannot be controlled, the cleanliness of the place can definitely be improved.
All in all, we gave the place 3 stars as we were still able to get the rest we needed, and had no other issues with the apartment. However, due to the location, crowds, cleanliness, and noise, it is not likely that we will choose to stay here again.
