Koichi’s place very easy to find and easy to check in to. The house itself is well equipped with all you need. It’s in a quiet area so you’ll sleep well.
The location was excellent and was just a short 5 minute walk to the nearest Subway station. It’s also still a walkable 20 minutes to the main Shinjuku centre and station area.
There are also plenty of restaurants and grocery stores in the area. My favourite was the beautiful Shinjuku Central Park which was peaceful and a great to sit and plane watch.
10/10 would stay again.
