We really enjoyed our stay.
Visiting the Tarxien Temples, Hypogeum and also (small food) shops is very easy since it is so closeby (walking distance).
We parked our car on the road in front of the house. There was always parking space available. Public transport to Valletta was also very easy (walking distance to the bus stop). Upon request, we received good information / tips about the islands from the owners.
We had our "private" entrance via the garden door. The apartment and surroundings (garden) are very convenient and beautiful. We really liked the fact that we actually (unexpectedly - since it is the owners' property and they also live there) had the pool all to ourselves. There was a bathroom downstairs (e.g. for a shower prior to / after swimming). The appartment (which also has a bathroom) is upstairs; the beds and couches are comfortable; and there is a good working AC but the big windows (with a marvelous view) do open as well, which is nice at night when it becomes a bit cooler (fresh air). The kitchen is downstairs, which is convenient for breakfast/lunch/dinner on the terrace.
It was very nice to have a chat with the owners but they also respected our privacy. The pets were very calm.
