The only nice room in our apartment is sitting room and I’m not enjoying being in a bathroom, kitchen or bedroom. I just want to decorate and fix everything, but it costs A LOT. And I’m on of the annoying people who wants to do everything perfect!! And then it costs even more. I just don’t know what to do and where to start 😤😣
