The pictures are true to the actual apartment, the AC was good and it didn't take long to cool down the apartment even after a whole day out. The AC does sound a little bit but we could easily sleep through it. The bedrooms are quiet as others have written. The beds are quite hard, but I guess it's the same everywhere in Malta. The pillows were large and comfy though.
The check-in consisted of a key in a locked box, simple and easy. The key to the apartment itself is quite hard to lock the door with.
The elevator is working again and that's good because the stairs are quite narrow so it would be a bit hard and heavy to get luggage up without it.
The apartment is close to the ferry to Valletta, several bus stops and restaurants, small shops and a supermarket. If you want to rent an ATV or a scooter it's just outside.
The really only negative thing was that the last two days we had no water in the bathroom. Not sure if that was a problem with the apartment or with the whole town since Sliema lost all water for a while, but we heard people showering even when we had no water in the bathroom and after the water in the kitchen had come back for us. The owners tried to solve the problem even though we first discovered it late at night.
The WiFi reception is quite bad in the bedrooms, but great in the living room. It was the same with 4G though, so I blame the stone walls.
The floor of the balcony was quite dirty from all the dust outside, but the rest of the apartment was very clean.
The owners were very kind to book a taxi for us in advance for when we first arrived to Malta, the taxi cost us 20 eur from the airport to the apartment.
