It was so fun solving the ten lines that I forgot about the flat mates constraint until I was almost finished and got stuck. Very nice!

I honestly found this the hardest of the series so far. Beautiful setting but challenging.

love some some ten lines. Very nice and surprising interactions with the dutch flatmates.

I always forgot about the Dutch Flat Mates rule (read the title, buddy!). Would have made the puzzle much easier, I guess...
Very nicely set, thank you!

I am not sure if I have solved in the expected way, but several points were very nice, including the break in box 1.
