Barceló Fortina Malta in Sliema

I recently stayed at this hotel and, while it has some strong points, there were several disappointing aspects that affected my experience.
Pros:
The location is excellent — close to shopping malls, restaurants, and tourist attractions.
The room itself is spacious, which is a big plus.

Cons:
The slippers provided were both for the right foot, which was inconvenient. =＞ I got them changed
Bed sheets and towels had an unpleasant odor.
Housekeeping was incomplete: only the bed was made. Trash was not emptied, coffee and water were not replenished, and the bathroom was left untouched.
Maintenance issues: the faucet was extremely stiff, and there was even a power outage around 10 PM one night.
Switches were poorly labeled, making it hard to figure out their functions. The hairdryer was hidden in such an obscure spot that even staff couldn’t locate it without video-calling a colleague for help.
The hotel refused to provide any service for heating food.
Plastic cups were provided, which felt cheap and lacked quality for a 5-star rated hotel.
Despite turning on the “Do Not Disturb” sign after being woken up two mornings in a row around 9:30 AM, housekeeping still knocked on the third day.

Overall, while the location and room size were great, the lack of proper housekeeping, unclear amenities, and maintenance issues made the stay far less comfortable than expected.

Must seen before you book the superior sea front room.
(a) I stayed for 3 nights and Room 233 assigned. This room and also the neighbour rooms have grave privacy problem. These rooms are at the same level of a busy foot bridge. The nearest distance between the room and the foot bridge was just the width of two vehicle lane, that means everyone in the footbridge can see what happens at your room clearly, especially at night!
(b) about 1/4 of the sea view was obstructed by the footbridge and most important was that the view of the famous Saint-John's Cathedral was severely obstructed ( unlike the photo appears at the hotel's web site which was deciving). You will hear busy traffic noise at your terrace also.
(c) I asked the staff at the front desk for a higher room due to severe privacy problem but she said the rooms in the same class were all full and could not help. As I would stay for 3 nights and seen if I could change my room on the second day or third day but she could not help also. I then approached the supervisor the second day at 9 am and the result was the same but the supervisor was more swift promising to find an alternative room for me and let me know by email soonest possible probably before noon as I had to go out. However
no feedback was received then and I had to come back to the hotel at 2 pm. Upon enquiry, the supervisor suggested a so called "premium room". Very big with a large terrace with city view but no front sea view. Due to grave privacy problem at Rm 233, I had to accept his offer but unreasonably I had to wait for nearly 2 hours from 2 pm to 4 pm for the staff to clean up the room (the check out time for this hotel was 1200 noon and I thought the hotel management should clean up this room first as there was a disappointed guest who was suffering from the hotel's lack of responsibility to provide privacy to their guest during their stay.
(d) everyday there are guest moving in and out but the hotel management just could not help to move me to a higher level room on the second or third day. Are they fulfilling their duties?
