Thank you Michal for your stay and thank you for the review.
Concerning the electric kettle, sorry if it was an inconvenience. We have always had an electric kettle and were sure it was somewhere in the apartment, but as it turns the last guest finally responded and said they took it with them!!!
We only found this rather late, when you were already getting close to leave.
We are fixing this problem and hopefully from now on, it will stay in the flat where it belongs. :))
