Stayed here a year ago as well, and my thoughts about the hotel hasn't really changed. The carpets still have the same stains, and I even noticed the white sheets have stains and holes... Maybe the carpets are hard to clean or replace, but white sheets should at least be easy. However, the place is really worth the price you pay. The rooms are comfortable, despite the lack of a fridge, and the staff are nice when approached. The luggage storage room had no more space, but the front desk was able to store our luggage for us.
Lastly, this has nothing to do with the hotel but some advice regarding the train stations. From JR Hamamatsucho, the closest exit is North, but you will struggle to get your luggage up or down the stairs. Either take the South Exit and walk a little more or find a way to arrive through Takeshiba Station, which is right next to the hotel. Hopefully when construction is over, there will be an elevator at the North Exit as well.
