Oh love, I am so sorry to hear about your Dad. You sound like such an absolutely lovely person, and family is everything isn't it? One of the integral members of our family is a step member, and he is absolutely just as important as everyone else, so I am really touched that you feel like that about your step-mum ❤️
I would love to give you some of my history, but it is too late for me to name change and I really don't want to be outed. However, I think that I can tell you that I was originally from one of the Home Counties, and have lived in both the North and the South of the Country, in major cities and in inland villages, and two seaside towns. My moves across the Country have all been because of my husbands' work, until my last 3 moves (that happened within the space of the last 4 years) they happened after my DH retired, and were down to a mixture of money - or rather the lack thereof, and another really important thing that would out me completely, so I just can't explain what it is, sorry. By the way when I referred to husbands' I was talking about almost consecutive husbands, there was a shortish gap in-between, but I didn't have two at the same time!
So I understand completely that moving can be something forced on you (well I could have chosen to split up with my husbands' - or not even to marry the second one, but I've a feeling that someone once "said" that "love conquers everything" and in my case they were right 🤭). So even though I love Poole so much, I couldn't stay there then, and I couldn't afford to live there now.
I think that Bristol is mainly a lovely City, and The Downs are brilliant - if I could have a house near the old zoo (I don't know if it has actually shut yet, but The Wild Place should be a much nicer (mainly larger) setting for it), or a house close to White Ladies Rd, or Black Boy Hill I would be very pleased - I know that those are horrendous names for this day and age, but I am not sure if we should whitewash these things, as that could lead to us forgetting they ever happened...
I also love the culture in Bristol, it is very varied, and all of the different types of restaurants etc.
When I mentioned Bristol previously I was comparing it to the massive cities that I have lived in previously, and if the OP is a home counties girl then she is probably used to what London offers, which is obviously on a much larger scale, more theatres, more nightlife, more shops, more green parks, more elegant hotels (for afternoon tea!), more museums, etc, but of course there are also more stabbings, more poverty, more crimes in general, more fumes, and the wonderfulness of black snot when you travel on the tubes everyday 🙈 So Bristol isn't really boring, it is just smaller, and probably these days a much nicer city to live in than the top 3 - in size.
If you need to be close to a station there is Yatton, which I don't rate all that much myself, and like you mentioned earlier Bedminster, which as you know has a railway station, and some of the properties on Bedminster Down have lovely views over to Long Ashton, which are especially good during the baloon festival 😊
And then there is Weston-super-Mare (when I lived in a flat overlooking the muddy bay, I loved it, but don't tell anyone on here that I said that!) I still stand by all the other comments I made about it! However, your mortgage broker is right about the houses on the hillside, and Uphill, but we couldn't have afforded Uphill. It is close to the hospital, but I am afraid I would beg to be taken to Southmead Hospital if I were ill or in an accident. If I could go into details I could back up my last statement with lots of horrible stories - they even gave my very old Dad PTSD. By the way, I don't know if they have got their 24 hour A&E back yet, I always found the Drs in the A&E department were very good, it was when you went deeper into the hospital that the bigger problems began...
Anyway, I wish you the best of luck in finding just the right location for you, and the ideal property. That last sentence goes to @LAHallucinations as well, and I also send her my apologies to for going off on a tangent x
ps. Worle High Street in WsM has IMO the best Chinese takeaway I have ever had, including from China Town in London.
