Definitely worth staying at, here's why:
-Location: it's literally a 5 to 10 minute walk to all the touristy parts of Shinjuku, really cant get much better than that espically after a big day shopping, the apartment is down a cute little street away from the hustle and bustle so it's nice and quiet and finally it's a hop skip and a jump away from a train station which makes it ideal for exploring the city.
-Check in: Super easy and the host sent out highly detailed information that made it a breeze to find.
-Host: Really great guy, had a very minor problem on the first day and he replied within 5 minutes, had it all sorted by the time we returned from our day trip. A++
-Apartment: Honestly, the best sleep I've had while staying in Tokyo, internet is superfast, has a small kitchen plus microwave, stove etc etc so whether you're eating out or cooking it's got you covered!
I rate this listing 5 out of 5 and wouldnt hesitate to stay here again the next time I'm in Shinjuku
