Jun's place was great in general. The location is very convenient, right next to the metro station 西新宿五丁目 and is within walking distant of the Shinjuku station. There are a number of convenient stores (including 2 Family Mart, 1 Lawson & 1 7-11) right next to the apartment and I think most of them open 24/7. However, there is no elevator in the building, so we had to carry our luggage and climb the stairs.
