Manami's place was great and located within a quiet neighbourhood! There were welcome snacks and little instructions around the house.
The music and vintage / unique / household / food shops of koenji are just a quick 5-10min walk away. Convenience store and bread store was just next to us!
We visited in late december and over the new year so it was a pity that most shops were shut for the new year.
Ceiling of loft was rather low so please take care when you climb up to rest in the bedroom. Bedding was comfortable and we had a great rest after exploring the city.
I recommend this place for young couples as you will need to climb up to reach the bedroom.
