Great place - has everything you needed and more. The washer/dryer, microwave and utensils were useful during the stay. Loved the view of skytree every morning, too! It helped that the lawson was just across the road for the late night supper walks. It's near the Hokusai museum and it's quite accessible to Asakusa and Akihabara by JR trains.
Just note that if you've got big luggage or long walking days the walk to the place and up to the apartment could get a bit tiring. Also, if you plan on staying here - remember to keep the lock combinations of the room key and door when you do your check in online or you'll be stuck outside trying to find the combination online.
Overall, I enjoyed it! Thank you for the pleasant trip.
