Hi no I wouldn't get that one. It's too small for a Syrian - it;s horrible when they photoshop a syrian hamster into something it can't possibly fit in! 20cm x 17cm is not a bad size for an OPEN house or hide but the compartments would be narrow and cramped for a Syrian and the entrance holes might not be big enough either. It does look like it might have a solid floor as well which isn't ideal as it would just get pee soaked and the hamster can't dig under it. It might be ok for a dwarf hamster if the floor was knocked out - but then it might collapse!
I had a look on Amazon.com.tr which I think is Turkey? There wasn't a lot came up in my search but there is this Karlie house - it's not a labyrinth/multiroom house but I think the one you linked is on the same listing. It's a nice corner house though and it comes in different sizes - 18 x 18 is probably the hamster sized one which wouldn't be that spacious - just an extra hide. But the next size up 24 x 34 is probably guinea pig sized and would make a nice large open house inside. However the doorway would be very large so the best option there would be to push it down in the substrate so the doorway is lower and the house is lower. I've done that before with a guinea pig house. I actually had it sitting on the cage base with the substrate piled up around it, and inside it so it didn't need supporting underneath. However - then he can't dig down very far inside it or tunnel under it - which makes it safe but limits his digging. With substrate inside it though, it does give him substrate underneath and the ability to burrow down and bury hoards.
So it could either be a large corner house (and I'd suggest putting a bendy bridge over the door to make a tunnel entrance so it's then darker inside and becomes a bit more like a labyrinth house) with the 22 x 34 size. Or you could get the 18 x 18 one just as a normal house and still put a bendy bridge over the door. I think they are quite light as well so the hamster sized one probably wouldn't need supporting underneath.
I have no idea what the prices mean so no idea if it's ridiculously expensive or not!
