Cooker is working, there is a lighter near the lighter and i wrote him several times that he should use the lighter but i guess the guest used to see cookers with built-in igniter:)
The hot water has not got any problem. Sometimes pressure drops down and a red light is blinking on it because the building is old. I asked Tom if a red light is blinking but he did say no. I think he didn't wait for enought time for the hot water outlet.
I have so many recommendations and instructions in my airbnb account for the visitors including hospital, restaurant, cafe, market, bar,museums... adresses and links.
There is a washer machine instruction paper above the washer which tells the guest clearly how to use it.
