This place was great - conveniently located pretty close to a fair few different train stations and train lines. Or, if you're happy to walk, you can access some major Tokyo attractions in under 20 minutes - Ueno Park (10 minutes) and Akihabara (15 minutes) being the closest of these (and the football museum too (5 minutes) which had loads of cool 2002 FIFA World Cup stuff!).
Ochanomizu, also about a 10-minute walk, is lined with lots and lots of guitar shops if you're interested in that kind of thing, or if you walk further on down to Jimbōchō you'll come across plenty of cool used book shops and arty boutique type places.
The Airbnb room itself was pretty accurately described and pictured and for the price I can't really have any complaints. Was great for me as a solo traveller but would be okay for two people too. No cooking equipment available though, but in my room there was a fridge, a kettle, a microwave and some crockery so I wasn't having to eat out all the time.
