The windows of the condo I had faced an extremely noisy lane at night and the windows didn't seal compounding the noise problem. The blinds didn't function well either. So sleep was hard to come by. The condo was fine, clean, nothing special but then its cheap so it was exactly as expected.
A different condo in the same building might have a different noise outcome, but I'd suggest if you are looking for inexpensive condo, try a different location.
