Before keep on reading: If you are thinking in renting Daisuke´s place and it's free, book it! and come back later. You won't get better price-quality ratio in Tokyo and Daisuke deserves his superhost title.
First the apartment: hyper clean, with absolutely everything you need, from soap to scissors to washing machine to detergent... with a lot of light in a nice building, easy to find with the instructions provided and situated in a very trendy neighborhood (Shimokitazawa) 5 minutes from Shinjuku JR station and very frequently connected. It's a very nice area to wake up in the morning or end the night with plenty of offer to all palates.
Then the host: Superhost Daisuke, accesible, friendly, with lots of advice about places to go both around the apt or in Tokyo. We were lucky of meeting him for a coffee and he walked us around. Did I say superhost?
Only one thing to have in mind: The area is lively at night with some music bars so you can listen to people in the street shouting from time to time. We slept with the air-con on and the low noise of it avoided us to listen to anything.
For us this was a real gem in our trip.
