My family and another family (total of 8 people) stayed at Jojo's place for 11 days. We had kids (ages 6-9) and we were so happy and pleased with everything.
This was our first time to Japan on our own (from Hawaii). With the language barrier we were really nervous of not staying in a hotel with a concierge to help us, but Jojo was like our private concierge! She went above and beyond to help us get to the house safely late at night and even showed us where the nearest train station was to help us get our train tickets. Her communication was excellent and she always responded in a timely manner. Knowing we had her for help with any communication issues was a huge relief for us.
We absolutely loved the location of the house. It was a quick walk to convenient stores and the grocery market which made it easy to get food and snacks. We really appreciated having the smaller Otsuka station nearby because it was an easy station to get on and off (one entrance and exit) versus the bigger Ikebukuro Station which was farther away and also very overwhelming with so many entrances and trains. Our kids had no problem walking these distances and we were even impressed that they could navigate by themselves through the neighborhood on there own after a day or two there!
The neighborhood is very quiet, peaceful, and safe. It was such a great experience to stay at a local residence versus a hotel.
A lot of the homes/apartments that we looked at only had one bathroom/toilet so having two toilets was key for us. Especially one upstairs because it made using the restroom at night much easier.
I would highly recommend this house and Jojo has a host. It's definitely worth it!
