I was wondering if I was gonna miss you next week, as I couldn't get a flight for a reasonable price and ended up in the Eurostar (was trying to do the same trick as last time and end up in T5 Galleries at least out of London). Looks like our path might would have crossed in LHR on Wednesday.
Enjoy Istanbul, it's a fascinating city and somehow it ended up being almost yearly destination for me lately with family. I'm sure if there wasn't an injury involved, I would be asked to look at tickets to go again right about now.... well maybe in the autumn.
