I would recommend LiveinAsia to anybody looking for a place in Tokyo. We were unfortunately delayed getting to the station but were greeted with welcoming smiles at Nishi Ogikubo station.
The apartment itself is very clean on arrival, and especially rare having two good sized bedrooms in addition to a separate living space which can also be used as a bedroom. We are a family of four with two young kids, but this place could easily fit more comfortably. Loads of towels, clean sheets and absolutely tonnes of cupboards for clothes and storage.
All the appliances you would need for a long stay and crazy close to a huge 24 hour supermarket. Great to push our little one in the buggy to get her to sleep at 3am!!
Extremely useful having a washing machine, there is a launderette next door but is only open until 9pm. I found that not all of the machines were working, but there was a place called Kona Coin just 2 minutes walk away that looks really new and well looked after, also stays open until 11pm. Only 100 Yen for 9 minutes drying, so 300 yen will dry a whole load.
Complimentary wi-fi was included in the price with a portable hot spot to take around with us too. It is limited to 500Mb per day, but even with some Netflix streaming for the kids we didn't come close.
I genuinely can't fault this apartment for the price. Thanks so much for a great stay.
