Very well located, short 10/15 minute walk to Valetta central. Beautiful streets where the Airbnb is. Very convenient little supermarket just around the corner from the place (the yellow shop), which was useful. A man named Mario was the contact for arranging the stay but we never met him. He sent a lady named Trisa to let us in and she was very lovely and helpful, showing us everything we needed. Mario was also friendly and helpful by text.
The apartment itself was clean and had all the basic utensils and amenities you would need. We even cooked a few meals whilst there. The only issue is that the bathroom is very narrow - we had to have the sliding door between the bathroom and the kitchen open to be able to sit down on the toilet comfortably. If you closed the door, your head would touch it and your legs would be at an angle! I am not sure how the space could be changed to be better though. Maybe the toilet and washing machine could be swapped.
Everything else about the apartment was good. There was however a lady outside who walked up and down the street every evening shouting in Maltese. At one point I went outside myself to tell her to keep it down because it was so loud and likely keeping the residents of the entire street up. As this apartment is situated on the ground floor, every passerby can be heard easily. We were ok with this however, as apart from that lady, there streets were empty mostly. I wouldn't let it stop you for such a well located apartment!
