Travel there and back was generally fine - the tram still works, the flights were smooth (although an hour delayed on the way home), and the flat was still here and un-burgled when we got back. I had done a quick video before we left, just in case someone broke in, but thankfully we won't have to show the insurers just how untidy it was when we left.
The central heating is now back on, and over the last two hours the temperature has risen from 12 degrees to 14. Despite my complaints on Facebook about the lack of snow here, I'm actually pretty glad it didn't get too cold while we were away. One year we arrived back to find it was 4 degrees in the flat (which is the point the anti-frost setting turns the heating back on) - and it took about two days to warm the flat back up to a decent temperature. This shouldn't take quite so long!
The only downers are technological in nature - me stepping on my laptop screen (as mentioned in a previous post), and the NAS telling me that one of the hard drives has died when I turned it back on just now. Thankfully, the redundant set up can cope with a single disk dying, so tomorrow I'll be heading along to our local PC repair place and buying a new 3TB disk and asking how much a new screen will be.
