Museu Memorial del Carbó Municipal de Nogata

Clearly not suited for more than 2 people, when it was offered for 4. The space is too limited, the kitchen is ageing, and the additionnal futons were slims as bed covers, impossible to sleep on them. The location is not particularly pleasant (both building and area), I see it convenient for a one-night stop next to Hakata station for 2 people. But at that rate it was the worst price/quality combo of a 3 weeks trip in Kyushu (including 5 days in other areas of Fukuoka).
