I finally got around to cleaning the basement to make way for our guests arriving tomorrow. The place wasn't really too bad, but it needed a run around with the vacuum cleaner and moving the bikes around a bit.
Oddly, the biggest challenge was finding space for the Christmas decorations. they had to go where the roof box was, that had to go on the cupboard which in turn needed moving from the dining room.
I think the final conclusion was that we needed to go to Ikea to get a wardrobe/cupboard for the basement to put stuff in, but that is not important as we bought a wardrobe for our bedroom instead. Neither of us really know how that all happened, but I now have a big flat-pack project to get done tonight.
