Lovely little flat. Namio is a perfect host - very responsive, clear check in instructions and everything we needed for our stay was provided in the flat (including towels, loo cool, toiletries, cooking facilities, oil, etc). Very comfortable beds and a lovely space to relax in at the end of the day.
Great location too - feels quiet and out of the way, but only a couple of minutes walk to the metro station and a twenty minute walk into Ueno and half an hour to the start of Akihabara.
