Lina is a great host, really friendly and helpful with tips. They have a lovely pet chinchilla, really cute.
The room is traditional japanese room which you need to sleep on the floor, the space is for two people maximum. The toilet and shower are two lever lower and the stairs are really steep, so it will a be inconvenient.
they provide a pocket wifi during the stay and we can bring it with us when we are outside. The house wifi is fine, low speed but good enough for browsing websites.
the location of the house is great! Lina's instruction to the house is really helpful. close to train station, really easy to go to shinjuku station. quite neighbours.
