What kind of room specifications should i look for when recording at home? A smaller room were the sound kind of echos or a larger room?

The best type of room to record in is a quite one....

On a serious note it's kind of hard to answer your question, I'm new to recording myself but as I understand it some rooms provide more reverb then others and depending on the humidity can make notes seem to hang longer etc etc. So it all depends what type of characteristics you want to add to your tone when you're recording.

But if I had to pick one a small room, with the microphone as close as possible to the source of sound is the best. It will give you the cleanest recording and prevent things like room size effecting your sound.

If you want effects like reverb you can just add them in when you're doing your mixing.

But take what I say with a grain of salt, as I said I'm new to recording myself.
It depends on what you're looking for. If you want the natural reverb of the room, listen with a room mic for what you want. If you want to add reverb while mixing, then you want a dry room and directly mic the guitar.

I tend to record in my bathroom, believe it or not. A fair amount of reverb, it sounds awesome.

Bathrooms have sweet acoustics, my dinning room is all hardwood so I play my acoustic guitar in there as well. Both rooms sound good for it :P
A treated one.

Depends on what you're going for though I guess. I tend to strive for a more dead sound and adding the room with reverb and IRs later, since that gives you more tonal control over the sound of just the acoustic. But, if the room sounds good and has nice natural reverb that doesn't muddy up the sound, or give you too much highs from all the reflections, you might as well give it a shot.
