So, how to start...
At the beginning, Sergio was really nice and was giving tips, very helpful and everything.
Few days before our arrival, he told us that the boiler didn't work, we were really worried about not having water, but then he told us it would work again, and that he couldn't find a plumber (it was the 24th and our arrival was on the 28th, I would think you could find a plumber in this time, but okay).
At our arrival, very nice appartment, nothing to say about it. The next morning, my sisters take a shower... of 2 min because the boiler stops. Okay we turn off and on, it starts then it stops. I tell Sergio, and he answers that he's away and can't find a plumber, just try again and hope it works. Long story short, we had to take turns to have 2 min showers and the last days we boiled water in a pot to wash ourselves. Great holidays! We would have been okay with that if we didn't have also the toilets clogged for the last two days. We had to remove again and again water raising (but not just water...) in order to avoid an overflow. When we arrived, water was already stagnating but as we had never seen this type of flush, we thought it was normal... but no. We are not pigs, and we didn't put anything in it (despite what he may accuse us now). Anyway we put our hands in the dirt during these days, which was really not what we were imagining during our stay. And to finish, the day we left, he "magically" found a plumber friend and didn't answer to our request about a financial compensation (after having no hot water for 5 days and toilets for 2 it would seem reasonnable to ask for that) I didn't want to leave a bad commentary, because he seemed honest (and I think I'm a little bit naive) but I wouldn't want an other person to have the same problem. Let's hope we just had very very bad luck...
