Check in was straight forward from the instructions shared with us and the room did the job, with most things we needed (we stayed for around 10 days so an extra set of towels so we could wash ours would have been great plus additional toilet roll!)
Unfortunately there was a bad smell like old cabbage we kept smelling which we realised was the tray under the washing machine, so we kept the window open as much as possible. When we used the washing machine it leaked a lot of water from the door but thankfully we were in so put a pan under to catch it and didnt need to do a second wash. we had to hang the wet clothes on 5 hangers and on our cases to dry as there was no airer.
The biggest issue we had was no hot water for a day.. we tried to shower in the evening but it was cold so we went to a local sento. After messaging that evening plus a fair amount of back and forth sharing photos of the screen with the host the next day and attempts to resolve the boiler as per their suggestions we were able to reset the system from a cupboard and then had hot water back.
Something we would have loved would be mugs for tea and coffee and a toaster, but we got by improvising as needed!
The lock box also malfunctioned so we had to meet to pass the one key between whoever was going back soonest, but the housekeeper came and fixed this on request while we were out which was appreciated
The area was quiet and residential, but walkable to Asakusa which was great as well as a few local shops for supplies and food and multiple station options
