I believe that having a properly working shower (there was no pressure and water was mostly cold) is crucial for a normal daily routine. Rude communication of the host also left a very unpleasant impression. Then I said about the problem, host replied that bad pressure is the problem of the house, not hers. After all, she added that probably we do not know how to use the shower. Well… Regardless it is problem of the house or not, host should make some improvement to their property and to fix the problem. Hope this will be helpful information for other travellers.
