The room was fine for the most part. The house is located in a residential neighborhood with no restaurants or shops nearby, which is somewhat inconvenient, especially because you need to buy bottled water (you can't drink the tap water in Malta). I ended up having to lug two large bottles of water from Sliema back to the room to make sure I had enough for my stay.
Communication with the host was not great. Some of my messages during my stay went unanswered. There seems to be a lack of communication between Lucienne and her son, as sometimes one checks the guest Airbnb message thread but the other doesn't. I got really sick during my stay and asked to have my checkout time extended to later than 9am so I could rest longer. Her son said it was fine, but Lucienne apparently wasn't aware, and she came to the room at 9 asking me to leave. After some prolonged discussion, I was allowed to check out later in the end, but it was an extremely frustrating experience.
