Unfortunately not a good experience. I arrived to find the place not at all clean especially the bathroom.. I messaged Diewert who said it must have been used since being cleaned and that he'd sort it when he finished work that evening so we couldn't actually use the place till late that first night which was pretty inconvenient. But anyway we were perfectly nice about it, these things happen but then the next morning we got up to make coffee only to find the water container full of mould and one of the glasses had sticky brown stuff in it.
I wasn't going to detail this because I assumed it was an unfortunate one off experience but I did request a refund through the resolution centre for 1 out of the 3 nights which seemed a fair and reasonable request. But Diewert never responded which is very odd, I can't imagine that this is the experience he would want his guests to have.
