Back again
We moved into a one bedroom unit because we had no other choice. (EX) Partner was working as a pastry chef and was in his last year of his apprentiship so money was a big issue. All we could afford was a small 1 bedroom unit.
The bedroom was big enough for our queen bed and baby's cot, plus a tall boy for all her clothes and wardrobes for our clothes.
As it was once i had DD i couldn't stand her to be in a different room from me so even if we had a room for her she wouldn't have used it.
A few times I remember moving her cot out to the lounge (just outside the bedroom door) when I went to bed, but all in all she was a pretty quiet sleeper. (My nephew on the other hand made so many noises in his sleep it was crazy)
We were there a few months before I had her so the lease was up when she was 9 months old. I reasoned that she'd just be crawling when it was time to move, except she was army crawling at 5 months, crawling at 6 and walking around furniture at 7, so by then the small little unit was getting too small very quickly, but still was never a major problem.
We moved into a 3 bedroom house when she was about 9 months and that was pretty good timing for us.

I don't think it will be a problem, you find you adapt to whatever your circumstances. If you need to be in a one bedroom then it will work for you.

The other suggestion is to try a baby hammock for the first few months that you can easily move around. If there are any problems with bubs sleeping in your room you can move them out to the lounge room if needed, but you'll probably find it will work well. Its usually the males that can't sleep well with all the baby noises!!

The other thing is that my (ex) partner worked night shifts so i was home alone most nights with her and found great comfort in having her in my bed or right next to me. When he was home he was so tired he slept through everything anyway.
