I like it. Loads of potential there. But it clearly needs updating. Not necessarily from style perspective, but the old furnishings and the low energy reading suggests that there may be a lot to bring up to modern standards. And if it's always stretching your budget...
OTOH the fabulous garden suggests that the person who lived there might have been someone who took care of their home, so it might be well-maintained, just not up-to-date. Could you live with that until you could afford to improve it? I could.
Location I can't comment on, because everyone's priorities are different.
Oh, and B4 looks like a box room. Perfect if you want a 3-bed with a study.
