The hosts were very hospitable, prompt and accommodative. The house looks just same as the photos but the host did not publish the outside of the house and the toilet which were the major down fall of the house...
First I'd like to comment about pros...
-The host!
-Parking fee reimbursement (parking was very close)
-The beds were comfortable
-Wifi was strong enough for the entire house for even my kids to do zoom sessions as well as pocket wifi was given
-Free rubbish collection! Most of the Aibnb houses are charging for very extreme amount for throwing rubbish so this was definitely a bonus!
Cons...
-The house was very very cold that we couldn't stay in the downstairs which consists of lounge, kitchen and the bathroom. We were forced to stay upstairs only in the room :(
-Toilet was very very small that when you sit down your face is almost at the wall, and was very cold then there's no fan or window so...the air can not be changed...
-The towels and the bathmat did not absorb any water at all.
-The aircon in the lounge did not work well.
-Cold wind comes thru the entrance and also the kitchen door.
-Staircase was very steep so I wouldn't recommend this place anyone who's got young children and senior citizens. My child who is 5 yo has slipped down. It is very dangerous as there's not even a handrail so it's a mission to especially come down on the stairs.
-Sofa was never been used as it was very cold to stay there.
Summary
Well, this may be the problem of the host and the Airbnb both. Airbnb needs to make the host to put up the photos of outside of the premises as well as inside.　Most of the Japanese premises are, I could be wrong, particularly the renovated ones from the very old houses which can not be a standard of living/staying in terms of insulation and for this case also the staircase being very steep that my child has slipped down even. The house was extremely cold and was not in the state of living in the downstairs. All the aircons and heaters didn't make any sense as the house was not insulated and the heat kept on going upstairs as there was no walls between the lounge/kitchen/entrance. I looked for a place to stay for 2 weeks for my family to study/work comfortably, meaning I needed 3 rooms with wifi (not pocket wifi) and at least 2 desks/tables to study which were okay until I reached the house and saw the actual house from outside. I had a bad feeling from the look of the house and soon as I entered my bad feeling became the nightmare...the house was way too cold to live and we couldn't really use downstairs at all. We were not there to go out to do sightseeing and all so we had to stay in the house most of the time as my kids were studying online and my husband was remotely working too. Staying in the house was nothing but the torture to stay in that cold house. On the other hand the upstairs was way too hot as all the heat was coming up from the downstairs. The toilet was again too small to even sit down especially for men and if he sat down his knees would strike the wall. What's more is they put up the sign for the guest to sit down and do the job in there...so my husband tried not to go to the toilet much due to that reason!
We were counting days to exit from this house unfortunately but if you do go at the right season which is not hot summer/cold winter then probably it may be okay.
Hope this helps someone to make a right decision and also the host to make the place better or upload all the photos at least!
