I find it disappointing that Lyra would suggest that the property was left particularly messy, especially since there were a few things we had concerns over when we arrived, such as:
(i) cobwebs in the dining area
(ii) crockery and cups left with coffee and lipstick marks in the cupboard
(iii) washing still unloaded in the bathroom/utility room
We chose to overlook the above after a chat with the friendly host and had an enjoyable stay otherwise, so it's surprising to hear this response especially when a cleaning fee had been paid in advance.
