Had a great stay! The check-in and check-out was extremely smooth, they were helpful w/ my parcel (pocket wifi). The room was squeaky clean and quite big for a room in Tokyo. The neighborhood was quite nice and accessible (5-7min walk) from the train.
The neighborhood is nice, but there is almost no night life (past 23:00) around the area and the choices are limited. As the trains close at 24:00, we needed to choose restos around diff JR Stations before getting back to the hotel. Also, a piece of advice-maybe consider getting your luggage delivered from the airport to the hotel as luggages (L or bigger) are quite hard to walk around with (1.5-2hrs commute from the airport) ‘cos the yellow tile blocks w/ ridges (for blind people & the elderly) make the luggages quite hard to pull around the pedestrian lanes.
TLDR, I would definitely stay here again!
Size of the room + amenities + customer service + quality for value for your money = all surpass the quirks I stated above.
