Thanks very much for staying with us.
I'm sorry you had a couple of issues. I'd like to respond to each in turn:
I have given the cleaner your feedback and we'll check more carefully after it's cleaned in future.
The wifi has a range extender in the middle bedroom, which for some reason was unplugged by a previous guest, and I didn't realise. I've now placed it out of sight.
The oven has been replaced with a new steam/convection/microwave unit, and instructions left for future guests.
