Let's be honest, large percent of families in Dubai use services of "illegal" maids and it is very rare that someone gets caught. Unless, someone very jealous who paid maid's visa fees reports you on purpose.
I don't think she has a preferred area. She lives in jumerah and we live in Dubai Marina. It took her 1.5 hours by bus and metro and she didn't mind it.
STAY AWAY from Dr Marc Mueller! My husband went in with one-sided hearing loss. Dr. Mueller told him that he was getting old and he should expect that. My husband and I trusted him because he was highly recommended. He waited a year and kept losing more of his hearing and told his GP who sent him to a different ENT doctor who found that he has a brain tumor! He told us this kind of tumor causes one-sided hearing loss and every ENT doc should know about it and perform an MRI for it. STAY AWAY FROM THIS MAN!!!!!
