Na`s place is an amazing and affordable base of operations if you want to be in walking distance of Akihabara (7-8 mins) - but also has a great train/subway stop within a few minutes walk to access great Tokyo with.
There's a ton of more traditional Japanese Izakaya's nearby, so for food you`re all set if that's your jam. Na happens to be the fastest host I've ever experienced in my years of using Airbnb's , with great communication and able to solve the minor issues that i was presented with, with ease.
As with most places in Tokyo. It's small, the walls are thin but you know that in advance when booking. It was perfecftly suitable for me, solo traveller for two weeks.
But if you're a couple on a budget, and you don't have 4 suitcases, then this would work just perfectly fine too.
