Before I arrived, I expected some difficulties in moving in this hotel with luggage. In fact, it was easier than thought. Japanese footpaths contain slopes which make towing luggage on a long walk an easy job. We can tow our luggage from Kuramae subway station all the way to the hotel without needs to lift it up. A walk across Sumida river is nice with Tokyo Skytree view that we feel obliged to take a photo when we crossed for the first time.
The premise has complete amenities including microwave in your room, which we used to heat-up frozen ramen/ packed meal set bought at convenience stores nearby for tomorrow breakfast. Laundry room consists of both washing machine and drying machine (with hot air). Bathroom facility is a bit old but is clean and in good condition. Other furniture looks new and clean. Our triple room has one small bedroom and living/dining area in another room. The bedroom is already full with three beds so it feel cramped if you have some luggage. As for internet, it has free LAN cable in the room, which we used with pocket access point to get WiFi connection for our moblie phones.
Overall, it's a very good accommodation given what we pay for, better than expected and complete our requirements for the trip.
Note: if you come from Kuramae/Oedo line with luggage, use exit A5 with elevator instead of exit A7
