How does orwell present victory mansions as a unpleasant place? In this extract

It was a bright cold day in April, and the clocks were striking thirteen. Winston Smith, his chin nuzzled into his breast in an effort to escape the vile wind, slipped quickly through the glass doors of Victory Mansions, though not quickly enough to prevent a swirl of gritty dust from entering along with him.
The hallway smelt of boiled cabbage and old rag mats. At one end of it a coloured poster, too large for indoor display, had been tacked to the wall. It depicted simply an enormous face, more than a metre wide: the face of a man of about forty-five, with a heavy black moustache and ruggedly handsome features. Winston made for the stairs. It was no use trying the lift. Even at the best of times it was seldom working, and at present the electric current was cut off during daylight hours. It was part of the economy drive in preparation for Hate Week. The flat was seven flights up, and Winston, who was thirty-nine and had a varicose ulcer above his right ankle, went slowly, resting several times on the way. On each landing, opposite the lift-shaft, the poster with the enormous face gazed from the wall. It was one of those pictures which are so contrived that the eyes follow you about when you move. BIG BROTHER IS WATCHING YOU, the caption beneath it ran.

First, the describes the awful weather that day even though it's already 1pm in the afternoon by mentioning theh character's need to nuzzle his chin into his chest in an effort to escape 'the vile wind'.

Orwell then focuses on the hallway's stench comprised of the smell of 'boiled cabbage and old rag mats', definitely not a pleasant combination of odors.

The author also makes sure to point out the lack of electricity has made the elevator useless and the character must struggle up seven flights of stairs while dealing with his varicose ulcer inflammation.

Then there is the invasive and threatening poster found at each flight of stairs with the ominous implicit message of 'Big Brother Is Watching You' Also the use of big captions has the effect of a muted scream.
