Hotel Lion d'Or in Heist, Belgium. 4 or 5 motorcars parked in the street at the front. The hotel is a tall building with balconies
Postcard from Heyst sur la Mer showing the front of the Grand Hotel de L'Univers, with images of interior rooms - the salon, the salon d'ecriture, chambre a coucher, and the salle a manger. The latter, with rows of tables in white tablecloths and patterned wallpapered panels is presumably a close match to the one in Marryat's novel.
Detail of the salle a manger - a room with dark wainscoting and patterned wallpaper panels, rows of tables with white tablecloths and delicate white pillars holding up a ceiling with gilt or painted detailing.
I'm writing on Florence Marryat's 'Blood of the #Vampire' (1897-same year as #Dracula). It starts in the dining room of the Hotel du Lion d'Or in the Belgian seaside resort of Heyst (modern Heist-aan-Zee). I've just found a hotel postcard from c.1910 & dining room of similar hotel down the street!
