House of the Day: 267 6th Avenue

Do a lot of entertaining? Need a house with a 90-foot-long ballroom, billiard room, bowling alley, and lounge with a 15-foot-long cocktail bar? Look no further. Built in the 1870s, this Park Slope townhouse was used by the Swedish American Athletic Club from about 1912 to 1970. Now it is set up as a triplex over a three-bedroom rental. An open house is scheduled for Sunday, May 19. How do you like the property, and the ask of $6,500,000?
