Having used several tube amps in my bedroom extensively over the years, i have come to the conclusion that if you want good tone in an hdb apartment, either get a solid state amp, or use good pedals.
The smallest tube amp i ever used was a Killer Ant. And my dad could hear me playing nightrain from 13 floors down.
The largest i ever used was a Ceriatone 5e3. And my grandma could hear that quite clearly from 4 blocks away at just volume 3.
A few months back i got a weber minimass, and guess what? When you turn down the volume to acceptable bedroom levels the amp sounds totally like....... a solid state amp.
People may diss the hell out of certain amps like the MG, but you have to understand that most of the haters did so as a result of attempting to use them in full band applications. Truth is with so many nice modelling and solid state amps out there on the market, if you still can't find something you like, your ears are either not working or you just don't know how to get good tone out of reasonably good gear.
