This is a basic, clean, convenient base to explore Malta. I would recommend this location over Valletta which is way too busy. Birgu is quiet and nice and so is Senglea just across the bridge. Fiona and Kenneth were very nice to deal with. It was a very hot few days but the aircon in the room is good and there is a ventilator in every room. There are some good places for dinner in the area: dCentre, Bebirgu, Osteria-VE. Unfortunately Tal-Petut was fully booked when we wanted to have dinner as it looked nice.
The apartment is very close to the bus stop (2 EUR ticket lasting 2 hours) and ferry to Valletta (2,80 EUR return). I also recommend the Taxify app, a trip to the airport cost 12 EUR (it was 20 EUR on the way in).
