All I could find on the web is the address: İncirli Cad. Davutkadı Mah. İncirli Taksi Durağı Yanı No:132 Yıldırım/BURSA. At this former bath house an active cultural centre showed, when I visited, that classical calligraphy and "ebru" (the marbling of paper) are alive and kicking.
The centre is situated along the cute tramvay rail-road in the Yildirim district that one should visit anyhow.
