i can not say i knew this man because he didnt appear at home. the comunicattion was not god because our e-mails rarely had answer. When the date for arrival was coming he sent us an e-mail saying his visa was not ready and he would arrive on 5th instead of 1st but finally he didnt come . Really it wasnt a good experience and i think for next time he should think a little in the problems that his behaviour means to the rest of the people :(
