The Meresti Metro station is a cleaned up and slightly modified version of the other stations found throughout the Capital Wasteland. The rail pit has been filled and leveled with debris, then boarded over. Atop the boards and around the platforms, numerous benches, tables, and beds for use by the various followers of The Family have been set up. The benches are placed in rows similar to a church's pews, with the lobby above acting like a chancel from where Vance deliver speeches. All of the group's members can be found here, with Vance and his wife Holly looking down on their followers at the platform below.
In the southwest corner of the main area is Karl's shop, above which are the Family's makeshift bedrooms. West lies the hallway leading to the blocked-off exit to the surface. In this hallway are also Vance and Holly's room as well as another locked bedroom (electronically locked by a wall terminal) in which Ian West can be found during the quest Blood Ties.
A mini nuke can be found in the main Meresti Family base on top of an overhang. From where Vance stands on top of the mezzanine facing the common area below, there is an escalator on your left. Stand about half way down the escalator and you can just barely see it on top the overhang at the far end (it's above the workbench). Placing a gas tube on top of the meter in the corner and shooting at it from distance will get it down. Finding the mini nuke afterwards might be harder since it might land far away.
A copy of Lying, Congressional Style can be found under the box on top of the train carriage under the place Vance is usually standing, by dropping down onto it from above.
Vampire's Edge can be found in the Hard locked sword cabinet in Vance's room (Vance carries the key).
Merești is the name of a commune in Harghita County, Romania, a part of Transylvania. This is fitting considering the overall vampire theme of the events that occur in the vicinity of Meresti Metro Station. Justin, one of the Family, makes note of this.
