Hi,
You might die of boredom in Goya.
Since you?re 28 I would recommend Justicia (aka Chueca) or Universidad (aka Malasa?a). Unless you?re more of the posh type, in which case I would recommend avoiding Malasa?a.
However, if you?re going to be entertaining for your company, then you might consider La Latina. La Latina is an interesting neighborhood but it doesn?t have the bohemian/university angst of Malasa?a (I like it but it?s not for everyone) or all the fashionista attitude of Chueca (fun but it can get tiresome sometimes).
I?m 28 myself and live in Chueca. It?s a cool neighborhood and many of the residents are young professionals, but the neighborhood is very noisy. In fact, all of Centro is pretty noisy, but hey, that?s what earplugs are for.
Regarding the subway, Madrid?s metro system is really great, so I wouldn?t discount it just yet.
Good luck.
