Hotel is overall ok. Clean beds and decent space for four. However, do take note if you are travelling with heavy/large luggages:
1. No elevators. The apartment is relatively high (mine is on the 5th floor)
2. Extremely narrow and steep staircase/corridors (barely enough for one bag)
Others:
1. Low water pressure
2. No dedicated sinks for bathroom/toilets
3. Unpractical power outlets
Otherwise, if you are travelling with light baggage/in a small group of 2, this is a good choice as it is close to the train station and Akiba electric town.
