Её комната в другом доме.

The accent is on the wrong syllable on “другом”. It wrongly accents the first syllable which is a different word (instrumental case of “друг” = friend) whereas this is the prepositional case of the adjective “друго́й”. These mispronunciations are extremely common, I’d say around 10% or possibly more of the exercises have them. Can someone please go over these one by one and fix all of them? It is really abrasive and is a major hindrance to learning.
