We had a wonderful Time in Maria's house. Our group of four had plenty of space in the apartment. The central location was perfect for walking around the main attractions of Valletta - we were even able to walk to the bus station to see other parts of the island.
Unfortunately, we were not able to meet Maria, but the caretaker Sabrina was extremely helpful and welcoming to us - even when we called her about questions throughout the weekend. She even went out of her way to call us a cab on the morning we left to make sure we did not get ripped off. I would recommend this location to any group visiting Malta!
