Very complicated feelings. Location was great. The house kind of matches description. Compared to other houses in Tokyo that we got to visit on this trip it is larger.
However, it was still quite small. For five people (including baby) it was not enough space, even just to sit together for dinner. There was no space for the baby to properly crawl around and explore. Felt a bit like a prison cell and the baby was not happy about that.
Additionally, the safety rail provided by the host (presumably for the attick) was broken or something, so the attick could not be used. The baby high chair was like a torture device. The baby was very uncomfortable and did not have a good appetite sitting in it.
When we arrived, the house was extremely dusty. It triggered dust mite allergy for myself and the baby. Basically it ruined the whole day because we were sneezing. But the host was nice to send a cleaner. This solved the issue.
The kitchen pots were old and we had to buy our own in the end.
