zoe: its easy to arrange lit at serum but you'd need to email them about whether they'd advise it for you given your history and what your LAD levels are.... they only like to give it to patients who they think will benefit from it. Its only your DP who needs screening bloods and he can have them there the day before the LIT. I think they are about Euro90something. Its on a sidestreet (and the sign is pretty small) so its not all that easy to find so you could either get a taxi from the airport - about 35-45 Eu, or you could arrange with their driver, John, to fetch you from the airport - about 60eu - or you could get the metro to ampelokipoi - about 15 mins walk away for about 6Eu. Once you know where it is, its very easy to find!
