What do you guys do, to make your home / house / apartment female friendly?
Interesting topic.
Let's start by zooming out a bit. I have said on this forum before that it is the combination of looks, money, status, and personality that attracts and retains women.
Your home (regardless of housing type) is a reflection of the money part of the seduction equation. Money is a relevant consideration at all ages, but does become more relevant for men somewhere between ages 30-35. It is more important in seducing women who are substantially younger and the women closer to their own age. Women near his own age will start to evaluate him on his providing skills, especially when she has a ticking biological clock. However, I have noticed that even 30s/early 40s childless women who don't prioritize having a child do start to care more about men's money/possessions.
The exterior of the home and local tastes in your region will matter. In some regions, older housing stock is frowned upon. Living in an older home (any type of housing stock) will be considered less appealing, no matter how well you do with the interior. In the United States, women in bigger cities in the Southern cities tend to frown upon older homes (especially older apartments) because there's been a lot of newer development in the last 40 years in these areas.
At 35+, a man will need an above average apartment at a minimum to get laid in a bigger city if he tends to deal with bougie, college educated women. Being some sort of homeowner also tends to help, especially if the home is a nicer home. Owning a mediocre to subpar home probably won't help too much in attracting women. Prior to 30-35, a man can get away with having an older, more mediocre apartment and still seduce women.
On the interior of the home, men will get judged for their home furnishings and home technology. One good thing that men can do is to make sure that they have home furnishings that fit their spaces and make sure that none of their home furnishings/technology look outdated. It is also good to keep mattresses comfortable for sex.
Keeping the interior clean and smelling good matters most for middle of the bell, non-Chad type men. If you are a 85th-90th percentile guy on looks (Chad type) and younger, this won't matter too much. I know a guy who was 6'0"+ and fit who kept messy apartments. He was able to get a lot of short term sex (usually one night) with his messy apartment. I think his messy apartment likely caused him repeat sex from his same night sex at the bars but he was able to get into a LTR and marriage with an apartment that wasn't clean at all.
