The heater button was hidden in the closet while it was not on in -3 degree weather. Bed was couch made so spring was sticking out. I was going to a business meeting after shower and there was only 10 seconds hot water then immediately cold water in a no heating on extra small room (not as described as the picture).
It was horrible experience. Second day the partner of the landlord came to fix the boiler and he was nice but landlord only wanna return 35 euro for first day while I paid 2x100 euro a day. I think it's about responsibility and compassion. Very unsatisfied. Could have got sick but luckily not because I sport all the time. I simply think the landlord should hold more responsibility for facilities or even compensation insurance.
