What is the meaning of this phrase: "a house in the middle of Paradise"?

The Prophet, peace and blessings be upon him, said: "The parent is the best of the gates of Paradise," and "I guarantee a house in the middle of Paradise for one who abandons lying, even if he is joking." The scholars have interpreted "the middle of Paradise" in these hadiths as referring to the most just and best part, as in the Almighty's saying: "And thus We have made you a justly balanced nation." Some of them said: The intended meaning of "middle" is spaciousness.
