If you want to travel throug whole country and stay near to Valletta, San Giljan and Sliema I can fully recommend this place. You can take a bus or go by walk to lot of cities. And also price will be better than staying in bigger city.
Nicholas is very kind, we communicated only by mails, but he replies in few minutes so communication is great.
Apartment was very nice and clean.
We needed only bed and shower, but there is also very big nice kitchen.
From my side, I have no negatives, only positives so when I will come back to Malta I will try to book Nicholas's apartment :)
