Martin is a nice and genuine host. He tries his best so the guest has a comfortable stay. However, he is a recylcler and a tidy hoarder. So keeping many stuff at home makes it very difficult to manage and clean. The whole toilet needs to be bolted or glued to the floor. I am surprised that this problem has not been sorted.
I have now seen previous guests also mentioned these problems. So Martin needs to fix them or get them fixed. May be installation of a new toilet is a solution.
The tap in the kitchen has to be fixed. The wifi should be placed in a location that the guests can also use it. When the guest room room is closed , you can hardly pull any wifi signal.
