The apartment is located in a nice place in Valletta. It's fairly easy to find a parking space in the ringroad below, not very far from the apartment. We visited in February and it was quite cold, fortunately there's are conditioner / heater in the flat which helped a lot (a stone house like this is really cold in winter without heating). The covered balcony was a nice feature as well, it offered a glimpse of what this looks like from inside.
One thing I didn't like was airbnb's commission: they charged 15% of the rental price. That's hardly acceptable, I'll try not to use them in the future.
