Overall, we enjoyed our stay very much and would recommend this AirBnB. In the following parts I will express my experience more detailed.
Very beautiful flat which is located in the heart of one of the medieval cities of Malta named Senglea (Isla). You will get to Valetta easily by the cheap ferries.
The equipment of this AirBnB is astounding. From a dishwasher & washing machine to a microwave this flat provides everything you need to stay even longer. The WiFi and AC also worked really well and Netflix on the TV was also a nice addition, which provide you with a nice environment to relax a little after long days in the warm climate. Furthermore, the non contact check-in was very easy and communication via WhatsApp was quite efficient.
However, there are also points to criticise.
There are not enough knives available, if you want to cut meat and vegetables simultaneously you will have to cut with a bread knife and a blunt knife.
Furthermore, during our stay there were ants on the first floor which were roaming all around, but were not too disturbing and should be cleared easily.
Lastly, the windows are not tight. You will hear anything that is coming by like the cars or the planes and if it rains, the water will come from the balcony through the bedroom door.
