Hi, are you sure this amentity is not vandalism? I mean usually it's discouraged to map private toilets and this is the only building with Tiilahkmõ talu name here. Maybe someone just didn't like them.

Yep, it's the same guy who renamed many names starting with Siidri to Piidri and added toilets at cider making places. 

I think there is way to create a note in StreetComplete instead of answering questions.

I'll remove the toilet from this building
