I've had my 3 at home in a pool, thoroughly recommend it. So calm. So lovely that when the midwives go home you're in your own home and space. You cannot beat the feeling of picking your baby up before anyone else does. Also, the pool made me feel quite dignified. I felt as though I was covered up, iyswim.
With my 1st, it was fantastic, and I was the only one of 12 or so in my ante-natal group to have had a good first birth (isn't that sad?). I think some of that is that if you stay at home you take responsibility for how it will be, whereas in hospital there is sometimes a mismatch of expectations.
2nd also fantastic. We recorded this one (for our eyes only) and what shocked me on watching it back is how mundane it seemed almost, in that she was born so calmly.
With my 3rd, birth itself was fab again, but it turned out that there was meconium in the hindwaters, and she'd swallowed some. Rather dramatically, when the cord stopped pumping, she stopped breathing and turned blue. Midwives quickly cut cord and one started with the artificial breathing, which she needed 5 of, and then was ok again - a worrying 30 seconds or so. I was still in pool with other midwife reassuring me. She was a bit "grunty" after that so we went into hospital just to get her checked, but no panic. She managed her first feed in the ambulance and the last of the green foamy meconium came out of her nose, and she was really fine after that. Basically, they had the same equipment available at home as they would have had in hospital, so she was at no greater risk. And would we have had 2 midwives present in hospital? I'm not sure.
I hope that story doesn't scare you! It's something that would have happened wherever and I think it's a really positive story of how well "adversities" are coped with wherever you are. It felt positive to us anyway, and if I had another, she'd be born at home too!
