There was an issue with access and that was partly due to the fact we had an extra child which was not accounted for in the original booking. It was also due to the fact that there was not any information on where to get the key sent with all the other information. Luckily, we had a data SIM card and could contact our host. Otherwise it would have been difficult. Eventually we gained access to the apartment and we we had a good stay. The apartment is conveniently located and it's definitely a good value stay compared to other apartments we have seen available. Thanks Naoto!
