Thanks Cuz for the info.
Will contact Polaris again. The problem is that despite booking flights for the 26th to 29th Nov Polaris say that they cannot obtain the NIE certificate during these dates and we must do so ourselves, however these are the only times we can visit this side of christmas.
I don.t see much point of making the effort unless guaranteed to obtain the document within the 3 days. If I can achieve this then I would be extremely happy.
Apartment is in block ten.
Thanks again for your reply
