Tatsu San was not only very responsive but also warm. He gave us tips and all before our trip. I did not have to reach to him during our stay because the directions were exactly correct and accurate.
The place was neat and cozy. Small, but typical for Tokyo. It would be pretty spacious for 2 people, just right for 3, but since we were 4, it's a bit of a stretch.
But that's alright since we were out most of the time. Location is great. It's a 3 min walk to Golden Gai, 7-10 min walk to Memory Lane / Piss Alley / Shinjuku Station, 5 min walk to Don Quijote. We got all we asked for.
What stood out is its design. It was very sleek and picture worthy. Extraordinary!
For room for improvement, just a very minor one, it may be good to include English instructions for the AC remote as it were all in Japanese.
But all in all great place. Highly recommended for people wanting to party in Shinjuku and needing to be in Shinjuku station the day right after.
Thank you Tatsu San!
