Location : its close to main station (shinjuku). It will make it easy to go everywhere. 600meter from shinokubo station. Its korean area. Many supermarket and mini store.
Apartment : its clean and complete. If you add basic stuff like sugar, salt, coffee and tea. It would be perfect.
Size : its too small for 8 persons. You won’t have space to open your luggage. It would be perfect for 4-5 persons.
Ichiro responded promptly and he is helpful. A map would be more suitable for me than a picture. I suggest you ask for one. Bcoz when we arrive at 10pm and it was raining. The pictures look a bit different than real. Thank you for having us at your place.
