Communication ahead of time was frequent via the app, email, and WhatsApp. Check in was easy as long as flight time was provided to the host. My friend had to give a large window of time and ended up having to wait thirty minutes for the host's son to arrive.
Upon arrival, we got a full tour and map of the surrounding area.
We had a small room with two twin beds and enough room for two suitcases. There were two windows and also an AC. There were two toilets on the second floor by our room and two showers in the first floor. The spaces were clean and tidy, laundry was done daily, signs were helpful in the kitchen/sinks.
The location was average - easy to get to and from a close train station but it was a distance from any main neighborhoods. It was a walkable thirty minutes to Shinjuku for restaurants and shops. The entry to the house was easy and there was even a small terrace.
Two small bonuses, ice machine and sensored toilet lid upon entry to the bathroom.
Overall this was a fine place to call home for a few days but wouldn't have wanted to stay longer than that.
