Donia's villa in Sliema is beautiful, clean, and centrally located. The pictures don't do it justice - the kitchen and back 'yard' are beautiful. She was extremely responsive in the days leading up to - and during - our stay, and provided us with a list of local sights and restaurants to visit. Check-in was very easy (she arranged affordable transportation for us from the airport to the villa, and the driver let us into the villa).
It is a 5-10 minute walk down to the water and the main strip of restaurants and shops. There are also plenty of restaurants within a few minutes of her home. The neighborhood is clean, safe, and quiet. It was convenient to have the pool in the back for a relaxing day spent at 'home.'
The only thing missing from her home was a coffee maker - which she's already told me she is going to pick up for her future guests!
I would 100% recommend staying at Donia's to anyone that is thinking about it - and I would stay here again for a future visit to Malta.
