We stayed for 6 nights at Jason 's place and are certainly happy with our choice. Close to public transport, super markets, bars.... great central place to discover the whole island.
The appartement has all you need and the kitchen is very functional.
A bit noisy during weekends but nightlife is part of the charm of Paceville/St Julian's, so don't stay in this neighborhood if "zen" is all you're looking for. But recommendable if you fancy some nightlife yourselves.
Jason is a good, helpful and fast communicator before, during and after your stay.
