"Ellos comieron en mi casa."
Translation:They ate at my house.
Why isn't "They ate at my place" accepted? It isn't a literal translation, but it works
Because you are pushing the limits, and Duo likes things literal. Casa = house, place = lugar, and 'your place' could be an apartment or a dorm room.
Narrator on normal mode says: Ellos, but on the slower mode says Ellas!!! Anyone else note the same?
