Villa Vittoria has an excellent location, we stayed 4 days in mid August. From Rabat most places in Malta are a 25 minute drive at the most and the evenings are very enjoyable. The guesthouse has a public parking a 2 minute walk away and is very near the greek gate, Mdina gate and the walled city of Mdina, Domus Romana and catacombs.
It also has some very good restaurants nearby and is located on a beautiful pedestrian typical maltese street.
Our room was very spacious, had an enormous bed, a kitchen and eating area, all that we needed. There was air conditioning in the room, that we turned on occasionally. The decoration is very much in keeping with the house it is lodged in, good taste and a feeling of years gone by.
Bernadette was very helpful, was willing to receive us in the morning as the room was free, immediately solved a minor issue we found in the shower and even offered to mail me back the earrings I left after leaving.
I highly recommend it and would definitely go back if we travel to Malta again.
