Nobu is a great host. Information is accurate and instructions are easy to follow. Communication has been very prompt and easy through email.
The apartment is very spacious and clean with good sized bedrooms and good quality beds and mattresses - we slept well. We felt very comfortable while there. The kitchen is adequate for basic meals. The bathroom and toilet facilities are good.
The location is a short walk from the main areas in Ikebukuro (about 7 minutes) where you can find all manner of shops and restaurants. It's also easy to get to other locations from the main station, including locations out of town (we visited Kawagoe and Chichibu using Pasmo cards). Three grocery stores and a greengrocer are a very short stroll away, with one convenience store literally ten steps away.
Whilst relatively quiet compared to the main area, there is still some noise from the local businesses, which can be noticeable at night, but only because we were jet lagged and couldn't sleep. Once asleep properly, it didn't wake us.
Overall, this is an excellent find and we were pleased to have discovered Nobu's place.
