This project with few minor issues went smoothly from start to finish, involving some stripping of ceiling papers, removing partition, updating bathroom and shower room, etc.
We stripped ceiling paper in all of the rooms (two bedrooms, hallway, living room), removed cupboards in the master bedroom, leveled walls, filled and sanded down and finally painted. Although this flat refurbishment was only partial (no kitchen renovation, and bathrooms renovated only partially), there was quite a big load of rubbish to be removed. The building had very strict rules on noise and any disturbance to neighbours - it was a challenge in that sense (no complaints received from anybody).
And below are the images of how we progressed:
