So for context we are staying in lake como for a 4 day 3 night stay, I booked the apartment on booking.com for around £400 when we arrived the host told us that unfortunately after the last guests came the hot water stopped working, and because we arrived on Sunday he couldn’t get anyone out to fix it but would get on it first thing Monday, it’s Tuesday evening now and still no hot water and we leave in the morning, we are travelling with a baby so hot water is essential especially because there is an incredible heatwave here, unfortunately moving to a different accommodation wasn’t offered nor do I know if it was an option due to the remoteness of where we are staying, the host has been kind and generous, but I do feel we should be entitled to a partial refund due to not being able to wash our baby or steralise bottles etc fro 4 days. Am I being an arsehole as my partner thinks I am.
