How often do you use apartments?

When I use them, it's usually as a starting point for a single sim or a couple. Eventually they move into a house.

I used to really enjoy them, but because of certain bugs I haven't been able to use them anymore.

I only have one save with a sim living in an apartment. I like playing large families, so I need lots of space for my sims and most of the apartments are too small. I also don't like how the windows and the outside of the apartment can't be edited.

If I have Sims that I intend to travel, I will start them in an apt. Those archaeological trips are not cheap!
Apts also seem to have a fixed price, so I don't have to worry about artifacts in the inventory jacking up the bills.

I play rotationally so I like to have plenty of variety and some of my sims will therefore live in apartments. I'm not a big fan of apartments though.

I can endure them only for so long, before I move my sims out. Really can't deal with the restrictions and noisy neighbours very long.

Very very rarely so I can't technically say "never" but it's the closest option.
They are too restrictive for me and I feel trapped in them. I only really like 2 of them and sometimes (once every blue moon) I'd have a YA move there but I always end up moving them back to another world or to the couple of lots that are normal in the city if I really want to keep them there.
I use San Myshuno basically only for the festivals and food stalls, a cafe I built on a rooftop, and an elegant and hip restaurant that I call The Gallery.

I used to occasionally but never liked the lack of outdoor space. With seasons all my sims live in normal houses - can't be bothered with apartments anymore.

never. I like to build my own apartments. I also like to live in none high rise apartments.
as you can't have either. I find them useless, and extremely limited.

Rarely. If I do play with apartments I allow my sims to file their complaints about their neighbors with the house owner. If the neighbors misbehave four times more than my sims, then I evict the neighbor.

The main attraction of apartments in Sims 2 was how all my families in the same apartment complex appeared on and interacted with each other at the shared community grounds. That's missing in this game. Also apartments could be anything from normal apartment houses to castles, archaeological camps, prisons, cruise ships... there was no end to what you could build.
