Imo it has to be T1, they literally own a commercial building in gangnam
T1's is cool, but I like Liquid's Netherlands HQ quite a lot. Its relatively small but chill and located in nice place (I would assume). On top of that all the players have access to apartments rooms so they actually get some privacy if they want and when sleep etc. Much better than sleeping in hotel also.
