Yes, there’s probably not much to criticize
I don’t find the entrance in the basement bad. On the contrary, I grew up like that and liked it. Also with this orientation. I like hillside properties anyway. Unfortunately, we live on completely flat ground
Back then, our garage was on the left side of the house, with the terrace on top, and on the north side there was an extension of the terrace and the garden.
Somehow, I don’t like the views. But I’m also not a fan of floor-to-ceiling windows everywhere. Besides, I find the double-wing doors/windows somehow too narrow in proportion. I don’t like that. There’s more frame than glass.
Maybe I would swap guest with bike, bike with sauna, and sauna with guest?
Then the sauna would be by the ground floor shower and close to the garden, sofa, and fridge
That would appeal to me more, because you have guests less often than you use the sauna (at least we do).
