Actually, that point was not addressed in my post but I'm happy to give it a shot. :) I think Darcy meant 'the place' in general terms. Namely, the town of Ramsgate. Or, as Ramya says the neighborhood. I doubt Wickham was living at Georgiana's home. My impression is he was probably living in lodgings nearby(possibly on her expense. But I'm just speculating thre.) It would be highly improper for Wickham and Georgiana to live together. Actually, I wouldn't put it past Wickham but Georgiana, as young as she was probably knew the etiquette of society. Again,I'm speculating. Darcy was unaware Wickham was at Ramsgate. He went down to pay a visit to his sister and discovered Wickham with her. JA appears to leave some of these details vague. It would be difficult for her to write about any living arrangements of Wickham and Georgiana in a Regency novel.
