We've been very happy with the apartment in MSida.
The apartment is spacious, has a little balcony and even a table soccer (two figures would need repair). The highligt is the pool on the rooftop - on a few days it was warm enough two use the pool even in January. Only drawback are the thin walls next to the street, so I would recommend to bring earplugs - however after one or two nights you get used to it.
Recommendation.
