Had a perfect stay at Koichi's place! Conveniently located near Golden Gai and Shinjuku but far enough away that it was quiet, the room was spacious and comfortable. Koichi met us at check in and showed us how to work the room; there's also a handy booklet. Koichi was friendly, courteous and responsive the whole time we were in Tokyo and the pocket wifi really helped, especially when we encountered sim card problems. Would stay here again!
