Check in was smooth, the space is clean & quiet with a lot of helpful tips from the owner about nearby shops & places to eat. He's really responsive and responded to my messages in a blink for most of the time.
Everything is exactly as described, and it quite be a bit tough to walk from Ueno JR Station to the place. I've been warned & reminded to take taxi, but we still did XD. So this serves as a friendly reminder to everyone else who plan to take no taxi at all with huge luggages (it's still doable though).
