The flat has only one real window what makes it a bit claustrophobic. Lack of windows in bedrooms makes it hard to wake up as it seems that it's still night.
We were told that there will be shower gels so we didn't bring ours, while there was none. Don't try to turn on 3 heaters at night as you will be left with no power till the morning.
Besides these issues, flat is in a great location and the beds are comfortable.
