I have noticed recently on social media many people see maisonette/flats/bedsits/studio flats differently to other people.
For me a maisonette is a property that has an upstairs and down stairs but there's the same above or below you.
A flat is a property that's all on one level
A studio flat is where you have a separate kitchen and bathroom but your living room and bedroom is in one .
A bedsit is a room . That may had a small kitchenette within the room. Shared bathroom and possibly kitchen
I have seen people calling a studio flat a 1 bedroom flat . Or a maisonette without stairs . Its bugging me 🤣
