When we arrived we noticed that there was no hot water in the bathroom. The trick is to open the bathroom tap on fully hot and then the shower on fully hot for hot water to flow. This instruction would be helpful if the issue cannot be fixed.
The mattress does need a change as it was not comfortable, the carpet should be changed as it was stained, the bedroom window stains should also be cleaned.
Other than the above all was good and we enjoyed our stay.
