This was a very spacious apartment. It is equipped to fit 6 people comfortably but there are also mats for an additional 2 if you have a huge group. This might be a challenge with only one bathroom. It’s a great space for the value too. There were 3 of us and we were extra comfortable with the apartment. The only thing is distance from the main city-center of Tokyo. It will take much longer so be sure you are familiar with taking the train as the station is only steps away. It is almost 2 hours by train from Narita with several transfers. Taxis are super expensive (Almost $300 from Narita) so the train and bus are your best bet. Just give yourself enough time!
