good location (may need to lookup map it) as it right in the centre of the neighbourhood near the station. it has many convenience stores nearby including a Daiso, and much further up a 100 yen store. Had an interesting time sorting out the rubbish based on the type which is guided by the signs of the dustbin provided by Sumida résidence for the disposal services.
I would say it was a good experience and good accomodation for short stays in Sumida city
