Certainly a good view of that one, the odd contrail on that route is usually a K or RC-135 out of Mildenhall.
We used to be at the top of Centre Tower with an excellent panoramic view in nearly all directions, now on the 5th floor of a smaller office block with Saffron Square blotting out much of the sky. I have a great view NE across SE London, ideal for some surreptitious "plane spotting".
