Translation:This sofa is too big for our apartment.
I AM a native English speaker (American). And yes, I am thinking like a Czech person when I do these exercises and have to change gears every time I translate to English. So sometimes it comes out this way. What my question was about was "Can I use the word FLAT instead of APARTMENT?" When doing the timed strengthening exercises I try to use the shortest word possible. Most Czechs speaking English would always say "flat" anyways. Can you please add this as an acceptable translation?
