It was our first visit to Japan and Manabu's place was our first accomodation.
Location: definitely very near to Takenosuka (which is on the TS line). But bear in mind , TS line is not part of the Tokyo subway. So if you are getting a Tokyo subway pass, it will only cover up to Hibiya line. From there u need to pay with your IC card to Takenosuka.
Apartment: cozy and nice. We had a lil issue with where to hang our towels so we just hang them at the bunk bed railings. Basic amenities such as rice cooker, washer, kettle are available for use.
It might be a lil bit too noisy if you open the balcony door but no issue for us as we had our balcony door closed all the time.
Communication: Manabu is a good example of a super host. He replies very fast. And he also asked how we were during our first night. It rained heavily on our 3rd day and was very prompt in our asking whether there was an umbrella in the apartment that we could borrow.
We would highly recommend this place if you don't mind traveling slightly out of the Tokyo subway area.
