This is a great little airbnb to stay at. I do think it would be tight with 4 people. It was perfect for me. It is very close to the train station and local eateries/konbinis. The rooms were very clean. I appreciated the heat already being on and it was a nice treat to have the toilet seat be heated. The host was very responsive and met me upon arrival. She made sure I knew were everything was and how to use certain things. It made my stay very enjoyable. The futon and covers were very comfortable and warm. I had a lovely stay. Definitely suggest.
