I had 3 dungeons. The first was in Windsor, the small Canadian town near Detroit where I came from. That was in the 1980’s. The second was in Thornhill, basically a suburb of Toronto, which was famously raided in 1994. The third, from 1999 to 2002 was in downtown Toronto. The first was a house with the dungeon in the basement. The top floor was used for the escort service. It was near downtown Windsor. The second was a bungalow in a posh neighbourhood. All rooms on the ground floor and basement were put to use. The third dungeon was a four storey semi-detached house in downtown Toronto. About 8 rooms were in use by the time I closed.
Some dominatrices have cottages which are fully equipped. Some work out of apartments. Some have houses like I did. Some do outcalls or rent facilities for sessions. When I chose a location it was not based on the location itself, it was based on the availability of a place within my budget and with a landlord who was on side. If I was healthy and had unlimited funds and wanted to go back into business I am not sure where I would reopen and locate. All locations have advantages and disadvantages, as do all choices of a full facility or minimalist approach.
