I had a great stay at Bert's place in Sliema. His place looked just like the pictures, was very spacious, had lots of light and all the mentioned amenities. It was easy to communicate with Bert and he even provided a list of nearby stores for provisions and things. Just to note the building itself does not have an elevator, in case you have problems with stairs.
It is a quiet neighborhood to stay in which was good if you are looking to get some quiet remote work done (wifi was great). But the apartment/location itself a good central spot to adventure out to the other areas of Malta from. His place is about an 8 min walk to the ferry that will take you to Valleta and an enjoyable 20ish minutes walk if you are headed to St. Julians (ubers are easy to call/access if you prefer - about 8 min car ride to St. Julians).
