Marisa and Stephen are excellent hosts.
They kindly picked me up by car from my previous Airbnb rental, that was also in St Julians
They kept me supplied with fresh fruit as I was unfortunate to come down with a slight cold during my stay there.
I also had a number of great conversations with them re: local and world political events, sports and the benefits of on-line computer training!
The only downside, is that the local bus (route no 120) stops running around 20:00 (ish). So if your out late, in St Julians, you have the choice of a 15-20 mins uphill walk or a 5 min cab ride.
If I ever return to Malta, I will definitely aim to stay here again.
