We had a really enjoyable stay in Cat's flat in Valetta. The location is perfect, and the city is great. The flat itself is very nice and comfortable and is as displayed in the pictures. Cat was a great host, in contact regularly to see if there was anything we needed, dropped off fresh towels for us regularly.
There were a couple of drawbacks to the flat; as it is on the bottom floor you can hear people come in and out through the main entrance, which obviously can't be helped but can wake you up if still asleep. The other I found quite frustrating, which is that the flat has a large frosted window but no blinds or curtains. This means that in the morning the room lights up at sunrise and woke me up quite early each morning. Not ideal when on holiday and you want to sleep in. A curtain would help.
Other than that, we did have an amazing time and would recommend the flat to stay in.
