I travel to Malta for business frequently and first found the Juliani when my usual hotel (read: the Hilton) was fully booked and I needed to find an alternative. I haven't stayed anywhere else since, and wish I had known about the place sooner.
The hotel itself is rather newly renovated and the staff always extremely welcoming, service-minded and friendly. The rooms are nicely designed and clean. I haven't used the pool area seeing that I come for business, but it looks inviting and sufficient for a few hours spent by the pool. The restaurant/cafe offer plenty of comfortable spots to have meetings in, and they have a board room that can be booked at a very decent rate should you need something more private (or space for a larger round of people).
I am always surprised to not meet more business travelers here - it's truly a hidden gem. Great location, great service and very decent rates.
