Elevator doors has to be closed fully and correctly, or it does not work. Not all the guests are very responsible to close it well, so often you can not use the elevator and have to climb up to the 5th floor. Walls are thin and noise from other flats easily spreads in the flat. Additional sofa should not be supposed for 2 persons, its too small for it. Amenities (towels and blankets) should be provided for 4 people not for 2, when the host informed that 4 guests are coming.
