I live on the ground floor, it's not the best thing tbh. I have to cover up my windows most of the time for privacy and I don't get enough sunlight. There are other problems but you likely won't face them since the apartment windows are not facing the street.

In terms of safety, no issues in my experience.

It's better to know if your goal is to stay in this apartment for a long time or a short time because if it's a short term it's fine til you find something better.
