I expected not to like it (I often describe the 1970s, the decade of my childhood/teens, as The Decade That Taste Forgot) but I could live with most of it!
The bathroom I would mostly keep - love the turquoise, dislike the tiles. Yes it's a teak overload, but it's been done well, and the hall and staircase, with that leaded glass window is fab. The pebbled glass door in Photo 8 - I remember such doors (and that exact glass) very well.
Even if you didn't like the decor, the house has fabulous bones that you could build your own style onto.
