If you're fine with an air mattress you'd be more than welcome to stay with me, this time around. (Is Mike old/independent enough to stay on his own for a few days? If not, forget I mentioned this option. - I would love being able to invite both of you to stay with me, but there isn't the space, as I'm still living out of one not particularly big room in a flat shared with three other people. There's space for one guest, but that, sadly, is it.)
