The place is great! Access is very easy from the main road. On the main road there is a traffic light and 7-11 convenient store on the opposite of the road. Very noticeable. Right next to the traffic light there is a road. The main access is that road. Walk through that road and you will find an elementary school. Forgot the name but quite huge. I'd advise the host to also include this school as a navigation landmark. Quite difficult to point the exact spot, but the small road to the apartment is in the side part of this school. The apartment is around 20 meters from that spot.
Households working perfectly although it was a bit challenging to know which button to press (it was in Japanese letters). I'd also advice the host to write down instructions in other language on how to operate the aircon, water dispenser, etc. Some are easy to guess like the electric stove. In my case the aircon, which also functions as the heater, doesn't always work as expected. Some nights it work perfectly (blowing warm air), sometimes inconsistent, sometimes it took an hour to work properly. Considering it's winter, i'd suggest for aircon maintenance.
Beds and blankets are perfect. Especially the blanket as it gets warmer when we sleep.
Didn't use the washing mashine, so i cannot comment.
There is also an automated massage chair. Very relaxing to have your back and hip massaged after long walk.
Bathroom is great. It's quite small even for Asians like me. Unlike bathrooms in other countries which are usually bigger. Perhaps most bathrooms in Japan are like this. Quite compact and use every space efficiently. Warm water runs great.
Communication with host is also good. Very helpful. The host even visited the apartment to check on the aircon. Unfortunately until we check out we didn't meet the host to personally express our gratitude. I hope one day can meet them again.
The nearest train station is Hatsudai Station, around 1 km from the traffic light/ 7-11 store. The access to the station itself is not very visible and eye catching. Escalator to the station is from inside Tokyo Opera City (or Tokyo Opera House, i forget). Other access from sidewalk are stairs. So it'd be difficult if guest bring luggage.
Hatsudai station is in the Keio New Line. Only 3 to 4 stations exist in this line, starting from Shinjuku Station. Please don't go with Keio Line as it doesn't go to Hatsudai although departs from Shinjuku as well. Please be reminded there are Keio Line and Keio New Line. Take the New Line.
Hope this review helps other guest and improve the host.
