We enjoyed a very nice few days here in Okachimachi. Not knowing much about the area we were delighted to find a very relaxed, family friendly area - only a shortish stroll from various train stations which could then take us to any part of the city, and about 15 minutes walk to Akihabara.
The place is super clean and modern and had everything we needed, plus a bit more space and privacy for a family. Julie was very helpful, and even provided things like Suica cards if they were helpful which is a great touch.
