Anaxibia
Nestor is frequently referred to as Nestor of Gerenia by Homer. Gerenia is identified as being the site of Zarnata, which is the same as Enope, one of Agamemnon's Seven Cities.
Presumably Nestor was raised there and that's why he was the only surviving son of Neleus out of twelve. So, Agamemnon can be considered a friend to Neleus and Nestor grew up under his protection.
Some of the classical writers mention that Nestor remarried Anaxibia after the death of his first wife Eurydike. Anaxibia was the sister of Agamemnon.
Maybe Nestor regains the reign over the Seven Cities as a dowry from Agamemnon, thus restoring Nestor's kingdom to its former size. Therefore there's a chance that Nestor did own the wrong palace later in his life, though, of course, it would've been destroyed by Herakles earlier.
The proper palace of Nestor in our Pylos could just have been a temporary replacement, which means Nestor can be expected to have built a new palace in a different location.
