David's place in Shinjuku is great and David is a good host, he was responsive to our questions and requests. The location near Kabukicho is good, and very close to a the nightlife of Shinjuku.
The location was a little hard to find at first (down a side street, Maps wasn't particularly helpful) and is a little far from Shinjuku station (15+ mins) which we ended up walking to most days as Higashi-Shinjuku (the station closest) is on a different line. It was easier for us to just walk straight to Shinjuku than head to another line and transfer. The place is a little small, the two of us spent over a week and probably would've preferred a bit more space in the end.
Thanks for the stay David, much appreciated.
