Flat was very clean and all comforts supplied. Very convenient to grocery stores, restaurants and especially public transport (trains,buses). There is a direct bus service from Narita airport to Osaki west terminal right next to train station. It was only $34 AUD for two adults and very comfy and convenient. Plenty of helpful tips and instructions at flat too from Sayoko and emails.
Highly recommend staying here if visiting Japan and great value. We crammed so much in to our 10 day stay from this location.
