When my sister and I were looking for a roommate, we listed our room on SpareRoom and went to one of their Speed Roommating events. We didn't meet anyone good at Speed Roommating, but that was more because people there didn't want long-term leases or wanted to be in a different neighborhood than our apartment. A lot of great potential roommates found our listing on SpareRoom and came to look at the apartment, but we wound up going with a friend whose lease happened to be ending just when we'd need someone. I'm going to be looking for two roommates when our lease expires next year, and likely will go through SpareRoom again.
When I see the phrase "the ____ estate", I imagine a vast mansion in the country full of monocled men and high-collared women receiving letters about productions across the country and doing spit-takes at whatever they contain.
