I can only second this. I honestly had the best time of my (professional) life when I had a little room with the rest of my team.

Asking quick questions in such an environment is also not that much of a disturbance because most people are working on similar features at the moment and there's a high chance that they don't need to do the whole context switch to assist you. It's really highly productive.

For the times where you really needed some time for yourself, headphones work just fine. I wouldn't want to wear them all the time as even the best ones become uncomfortable after few hours, but that's also not really needed in a small shared room.
