We had a really good experience during these 14 days in Joseph's flat. Joseph was a fantastic host and he warmly welcomed us allowing us in the flat quite early since our flight arrived in Malta early in the morning. Then, during our stay he was always ready to help for any doubt or question we might had, and we became good friends.
The apartment is ideally located in the heart of Sliema, quite near to the seaside with fantastic views to Valletta. The house is a traditional one made of stone with a superb Maltese wooden balcony, it has a lot of character while at the same time it's been renovated to make it very functional.
Also, the area is very quiet without any noise at all at night. And it's children friendly, our 18 month old daughter really liked it.
I would definitely recommend it for your stay in Malta!!
