Pangoo's place location wise was good ~ close to Shinagawa station and many bus stops as well. Very very quiet neighborhood since it is located on the back side of Shinagawa station. Apartment itself was one of the most spacious place we've been to in Tokyo. Many windows for fresh air and lots of sun. It had very detailed items to make our stay very comfortable, especially the multi-prong extension cord among many items. Pangoo is very fast with replies on any of the questions.
Thing to note: uphill all the way from Shinagawa station to Pangoo's.
Exploring the front side of Shinagawa station was fun.
