The man admitted having sex with the then 23-year- old woman at the house but told gardaí it was consensual and that the woman had not shown any fear.
The 47-year-old man, who cannot be named for legal reasons, had pleaded not guilty at the Central Criminal Court to raping the woman at the house on July 5, 2010.
The jury of eight men and four women returned their verdict of guilty on the rape charge on day five of the trial after just under two hours of deliberation.
The man was last week found not guilty by direction of the trial judge Mr Justice Barry White on a second charge of sexual assault on the same occasion.
Mr Justice White thanked the jury for their service. He remanded the man on continuing bail and ordered him to appear before him next Wednesday in order to set a date for sentence.
Last week, the woman, who gave her evidence through an interpreter, told Paul Greene SC, prosecuting, that the man stopped her on the street and she understood that he wanted her to clean a house.
She said they drove in his car to a house where the accused touched and kissed her. She said she felt afraid and did not want to have sex with the man at the house.
The man told gardaí after his arrest that he thought the woman had been consenting. The accused denied he had gone to the town that day to pick up a woman for sexual purposes.
“This girl did not give signs she was unwilling in any way,” the accused man told gardaí. He said she had been smiling.
He said he had not taken advantage of the woman, harassed her in anyway or forced her to do anything she did not want to.
The woman told Mr Greene that she had been returning home from a cleaning job when the accused man spoke to her on the street a number of times.
She said she spoke no English but she understood the word “clean”.
She said she understood the accused wanted her to clean a house and when she decided to do it she got into his car. She said they arrived at a house but there were not enough cleaning products.
She said she started to clean the house and the accused man touched her hand and rubbed her ear.
The woman said he left for five minutes and she tried to open the front door but it was locked. She said the accused returned with a Coke and water.
She said he explained to her how she should clean and held her hand before moving her to a different room. She said she asked when he would be bringing her back to the town and he gave her €50.
The woman said she thought at that moment she would be going home but he held her hand and brought her upstairs. She said she felt afraid and asked the accused if he had children or if he was married.
She said he brought her to another room where he kissed her and took off her blouse and his clothes. She said she did not want him to touch her and said she would take her clothes off herself. She said that she had said “no” and told Mr Greene she said this “because I did not want”.
Mr Greene asked her what she did not want and she said: “I went there to clean, not to have sex.”
She said after he had “fulfilled his desire” his phone rang and he left. She dressed quickly before he came back and the man drove her back to the town where she lived.
