It a strong exaggeration to sell the apartment based on sea view. The view presented as part of the presentation is not true. Only if you are on the roof, which is not easy to access and this view does not exist inside the apartment nor on the balconies in the apartment.
Compared to other apartments in Valetta the price is too high.
Check in, communication, cleaning and heating is fine. But if you are looking for a view - then go somewhere else.
