My husband and I just returned from a long weekend with a group of friends in Malta. We had 3 rooms booked at Hotel Juliani and ours was the only one with problems. We were moved from our original room due to electrical problems, and our second room had a faulty window, which meant we heard noise all night from garbage trucks and street traffic.
We paid 80 euros a night, which included a food/beverage voucher for what turned out to be our favorite restaurant (Barracuda). The staff was friendly and helpful, but next time I'll go with a chain I know better. This place was good for what we needed, which was very little time spent in the hotel, a clean, comfortable bed and good location for a bus stop. But all that being said it's not a place I'll remember.

I should probably start this review by saying "do not go to Malta on Xmas" unless of course you want to do some photography (my case). Services shut down for the most part, restaurant prices get crazy and the place is a ghost town or should I say a ghost country. If not for the fact that I could take un-obstructuted pictures of the attractions and the lack of annoying tourists, Malta in the winter is a no-no.
Equally, the Juliani has it's pros and cons during the winter season and part of my review may not apply to other seasons. Location may be one of those cases; where it is great on summer but not that great in winter. St. Julians Bay strikes me as a place that is vibrant during summer but during our stay it looked more like the outskirts of a desert town. I would recommend instead the neighborhood of Sliema. On the up side, there is a bus stop right across the street in which every meaningful bus line stops. You can go almost everywhere without having to go to Valetta first to change buses.
Hotel amenities are very good, rooms are clean and modern, internet is free. Breakfast was not included but here is a tip that may sound strange; go to the McDonalds next door! No, it is not your usual McDonalds like in the USA. It is clean, cheap and great coffee.
Back to the hotel, the staff is great, very helpful and polite, and my only complaint is the high pitch noise that water makes going down the external pipes, it is loud, they should fix it.
My last comment about the Juliani is that while it is a boutique hotel, it feels more like a big hotel chain place, whether it is check-in check-out policies, breakfast or services, it quite didin't feel right when compared to other boutique hotels we stayed in the past. I am giving "five stars" because I can't complain about my stay, but deep inside I am not sure I would return to the Juliani. It was too robotic.

My husband and I have just returned from 5 nights staying at Hotel Juliani, and there was really very little to fault in the hotel. We paid 80 euros per night for a 'deluxe' room (their standard room). The room was a good size, clean and comfy and very nicely decorated. Although it wasn't one of the 'sea view' rooms, we could see the bay, albeit through a narrow gap! Dressing gowns were provided and there was a decent range of channels on the TV (including Fox movies if you're so inclined) as well as a DVD player.

Our rate was room only - you can also get a rate with breakfast included but unless you are absolutely certain you want breakfast every day, I would avoid doing so, certainly if you're travelling in a couple. From recollection, the rate including breakfast was either more, or certainly only a little less, than you would pay if you bought breakfast separately every day. If you don't have breakfast included, you can have a full breakfast (including full English buffet, pastries, fruit, cereal, cheese, ham, tea/coffee and orange juice) for 14 euros each, or choose just pastries and tea/juice for 5 euros 95. We only had breakfast on a couple of days so it worked out much cheaper to have the room only. Breakfast is served from 7 - 10:30 every day, which is good if you want to laze around a bit.

The hotel is right on Spinola Bay and within easy reach of lots of good restaurants. The hotel itself has a good, albeit pricey, restaurant called Zest which does Asian fusion food. It is relatively easy to get into Valletta on the bus (buses 12 and 13 go from the stop right opposite the hotel) although it takes longer than you would expect (about 30 - 40 mins) because the bus meanders somewhat. If you're not in a rush, it's quite possible to get all over the island and to Gozo on the bus, and a weekly ticket costs only 12 euros. We went to the Hypogeum in Paola, Mdina/Rabat, Valletta, Vittoriosa and Gozo on the bus (the latter on the bus/ferry) and although there was a fair bit of waiting around, it was all fairly straightforward.

In summary, Hotel Juliani is a really pleasant place to stay with good, helpful staff and an excellent location. Thoroughly recommended.

Amazing view over the bay. Location is good - walkable to all sights and restaurants.
Join the locals for BBQ around the bay at night!
Rooftop swimming pool is small but well kept.
Restaurant is excellent quality and clean with adequate breakfast.

Avoid using busses in Malta if you have a destination in mind! The bus stopped at the hospital on the way to town - for an hour - as the driver's shift ended. So he went for lunch and came back later to drive on! Despite this the hotel is amazing!
