Had a wonderful stay! Place was well kept, checking in/out with the keybox was easy, detergent for the washing machines is supplied (a small but seriously helpful thing), and due to thick limestone walls was very very quiet :) The windows also have shutters which can turn the room pitch black at will. Ian & Anna sent through some helpful local tips, location is excellent (about a 10 min stroll to get to the Valetta city gate).
Also note that water is not drinkable so you will need to buy bottles of water for yourself but we did find that there was already a cold bottle in the fridge for us on arrival.
