Had my second at home. I wasn't that fussed, but my midwives encouraged me and by the time I called them it was 11pm, my DS was in bed, I cba to go into hospital... so they came out.
Like you, my hospital was 7 mins away (blue lights), 15 by car. So I was confident that I could get to hospital in time if things went wrong.
I had 2 grade 7 midwives attend, they were AMAZING. My DD went back to back during labour and they really helped me through that: it wasn't more painful than my first birth (induced, hospital) but it did slow labour down.
I gave birth at 5am. The placenta didn't come straight out but they gave it a little tug (they asked me first), and out it tumbled. I was grateful they tried as otherwise I've had had to go into hospital. I saw above that the same situation occurred less successfully for another poster, so I guess it's a tricky call: to tug or to send to hospital for a manual removal.
After that, they ran me a bath, cleaned me up, made my bed, I got in and a few minutes later my DS woke up and trotted in to our room - and met his sister. That was wonderful.
The thing I hated about hospital was a) the push to medicalise birth and b) the after-care. Noisy wards, constant bright lights, too hot, no privacy, terrible food, stroppy nurses, no support. Being at home smoothed my recovery so very much. So that's why home birth worked for me; I was less fussed about the birth itself in many ways.
No pool. I genuinely don't care where I am when I give birth, I just want to be left alone to get on with it. It's 'work', I'm busy, I don't need a pool or music or lights or anything. Just time, space, encouragement now and again and a bit of help if it gets a bit much. And they look like a messy wet PITA if I'm honest - too much fuss.
Downsides: I had pethidine and G&A with my first birth. I swore blind the pethidine didn't help with the pain. Turns out it did! Definitely more painful just on G&A, which is all you can have at home. Although, as I said, my DD went back to back. So I guess you need to weigh up how well you deal with pain, and how you might cope with less pain relief and a potentially more painful or longer birth.
Good luck, I hope it goes well for you x
