We travel a lot and I would say that this is one of the most beautiful and unique places we've ever visited. Staying inside the walls of Mdina is really special and Antonio's home is stunningly beautiful! We stayed with Antonio for 4 nights. It's a very peaceful and quite place to stay.
The room is well equipped with a big wardrobe for hanging clothes. The bed is really comfortable (we both have back issues so a comfy bed is important). There is a sitting room with a desk and a lovely little private balcony.
Having heating was a must! We stayed in early March and some evenings were quite cold. There is a heater in the bedroom and a separate heater in the bathroom. The rain shower was awesome with plenty of hot water.
Antonio is a wonderful cook and provided great breakfast choices every day. He is friendly and knowledgeable about Malta and we loved chatting with him each day.
If you have a hire/rental car, be sure to let Antonio know because he has to apply for a special parking permit that allows you to park your car just outside Greeks gate and a very short walk to his house. There are lots of great restaurants within walking distance in Rabat.
We can't say enough good things about Antonio and his house. If you are lucky enough to find that his home is available you should book it!
