Perfect Gaming Environment.
The best place to game is one that the DM can make their own. If the Dungeon Master can control the sound of the room then they can set the mood. If there is a wooden table, dice will roll better. If the seats for the players are comfortable then they will be happier and focus more on the game. The perfect environment is one where the Dungeon Master can weave a story that the players can become attached too without being drawn back out by outside influences.
