Hi again Bassim,
1) In the first paragraph, remove the word "the" before "...part of the road led through an affluent neighbourhood".
2) "Storeys" is spelled differently in British and American English. Your usage is fine, but just for your information, in American English the plural would be "stories".
3) By "sun lounge", I assume you mean "sunlounger".
4) After the words "...he went to the photographer to develop", add "the" before "photos".
5) Instead of "They would still stay without a flat...", consider "They would remain without a flat".
6) Instead of "Society which could not provide a proper housing for their citizens was nothing but a sham", use "Society which could not provide proper housing for its citizens was nothing but a sham".
7) In your final lines, when you write "That night they went to bed early and did not talk with other as they used to", replace this with "That night they went to bed early and did not talk TO EACH other as they used to". To speak with somebody implies an extended conversation. To speak to somebody implies the opposite of remaining silent. Since it appears in your story the two have had an argument and are not speaking, "speak to" would make more sense.
8) In your last line, you write "...she had a premonition of something bad which was going to happen". The word "premonition" implies something that might happen, not something that definitely will. Therefore, you should consider using "...but her mind was racing. As she drifted to sleep, she had a worrying premonition". This way, your writing will be more effective and it will allow your readers to use their imagination, as they don't know exactly what this "worrying premonition" is, and they don't know if it will certainly happen. This will make your readers more compelled to read on.
I must say, Bassim, that I have enjoyed reading the last couple of parts of your story. Although you could use more interesting adjectives in some parts - instead of "nice" or "bad" for example - your vocabulary is generally very varied. Given that English is not your first language, your skill and proficiency is outstanding. You not only use English properly and well, but you also use it effectively to compose a flowing narrative.
