Get in there real close like. Yeah, that's it. See? Does the floorplan for this 3-BR, 2.5-BA, 3,344-square-foot Brookline condo have a hallway of any length or breadth? From where we peer, it doesn't appear so. Still, the Seaver Street spread built in 2009 and on the market as of Sunday brings a lot to the picnic regardless: formal dining room, library and family room that all open to a loggia overlooking the pool; a master bedroom so big it has a sitting room and two walk-in closets; and two underground parking spaces, plus fitness center, concierge and heated indoor pool in the building. But no hallways as best we can tell.
