Everything was good until the evening came and the house became very cold. The heating was set to 19 degrees, we asked to raise it, the host raised it to 20.5, it became warmer. However next thing we've discovered is that it's problematic for four people to take showers in the evening - probably due to low volume boiler, the water was only hot enough on the second floor for about 5 minutes.
That's how we lived for two nights. When checking out after the third night I noticed the heating was again set to 19 degrees :)
Yeah, I'm aware of the new Italian heating cap laws. However we were not informed about that prior to our visit, and turning it off for out last night at the place just felt like a way of cutting the heating costs. The house does not have a good thermal insulation, thus it's indeed very cold inside in the evening in late November.
And yeah, there were three tea bags and two dishwasher capsules for three days for four people.
