Thanks for a great hospitality.
We faced some problems but the host was really kind and always offered us help
Now gonna just describe some things about this place
Cons:
- There is no microwave that can't help making me sad cause a lot of food is "fast food" that you have to heat and eat. We couldn't buy anything like that at stores to eat in mornings
- There is no home internet, like a normal one, only a pocket wifi that has a limit 1Gb a day. For us it was a problem, especially in 2k18 when one pic is about 5mb+. Host bought us a sim card but um, internet in Japan is really really bad and expensive. Nevertheless the host did everything to help us, thanks
- According to some Japanese rules the third floor was closed and one of us had to sleep on the first floor, so he "enjoyed" lights of passing trains haha
- One key for 6 people. It's a headache, especially given the fact that usually I took a morning walk (alone), so I always had to wake one of us up and ask to close the door after me
- A lot of garbage have to be separated but there were only 3 bins. Other things we just kept in packages near bins
- Blankets are kinda strange. Using them I was just sweating, like it was too hot. Had to find a balance setting up an air conditioning. It's better to provide some light blankets instead of those heavy ones
- A pretty small kitchen table for 6 people
Pros:
- Quiet place
- Convenience stores are pretty close
- Metro is near

In any case thank your for everything. We enjoyed our trip and Japan is so great.
And guys, buy any metro card, pasmo or suica, whatever, they both work well
Wish everyone a good trip :3
And thanks to Momo, a really good host, always was worrying about us.
Any place has its cons, but I bet Momo will fix them all ^_^
