Flat is Nice and really closed to the city center. Even if There are some sex shops in the street, that is not an issue and it is nice.
Owner can pick up you at the airport and he is really nice.
But there are some issue to know: the bed in thé second room is really bad and could cause you back hacke. During our stay, there are some works and it was noisy from 8 am eaven on sunday.
