This book follows two characters, Leon and Tiffy. The book is told through their two point of views, each chapter alternating between Leon and then Tiffy. The plot without spoiling anything is that they've agreed on sharing a flat as the title of the book suggests BUT instead of just sharing a flat they also share a bed. Just not at the same time. Leon is a doctor who works night shift so Tiffy has the flat during the night whereas when Tiffy goes to work Leon gets the flat and bed. My usual go to books are wee cute love stories and you'd expect this book to follow that because I loved it so much but it got them elements while also a serious storyline. I loved the personalities of Tiffy and Leon. It felt like I had entered their world while I was reading this book. It was one of them books that I couldnt put down!! I gave it 5 stars on my Goodreads so it also got a 5 stars here!
