Not recommended.
The flat is located in Paola, which is not a very nice part of Malta. It takes about ~25-30 minutes by bus and foot to get to Valletta.
In addition to the negative point of the location, there is something even worse: mould in the bathroom. Above the toilet and in the shower. When we arrived, you couldn't breathe in the bathroom as the small windows were all closed and the smell of mould was extreme. There was no ventilation in the bathroom and the constantly open windows did not help. The bathroom was always wet from showering, which was a paradise for mosquitoes. We left early and changed to another Airbnb, which was the best decision to enjoy our holidays.
