We had such a fun time staying at Choco's place. It's a lovely, compact, apartment, with everything that we needed. We loved the little sweets and origami cranes that Choco left for us. Most of all though we had a great time exploring Koenji. Thinking we would be travelling into town every evening, we actually spent all but one in Koenji. There are so many great bars and izakaya's within several minutes walk, yet the flat was so peaceful. We would recommend Tensuke, where we had an amazing tempura egg, and まんまじぃま (CrazyxCoenzy) a cool Izakaya super close.
