I had to make this decision recently. I am moving into an apartment soon. It is all concrete though, so I think it might be different to the types of apartments you tried. I did think about moving into a house in the middle of nowhere but the thought of a single person living in a 4 bedroom house with a yard was just too ridiculous for me. Also, the windows of the houses were only a few metres apart so I am not sure it would have been an better. The other problem was that the demographic was very different to me.
