We stayed in Sonja’s place for 3 nights. It was a good base to explore Valletta from, being just under the Upper Barrakka Gardens and under 10min walk from the main town gate / bus station.
Really spacious living room, kitchen and wc downstairs, with a bedroom and an ensuite upstairs. Shower hot and reasonably good. Lovely stone features. Generally clean but kitchen utensils / glasses / crockery needed a wash before using. Amenities quite dated.
In February we were cold even with the shutters closed; electric heaters were provided but did little as rooms were so large. Bed not particularly comfortable and quite noisy when moving around. However, was quiet corner of town and shutters could block out all light.
Location is excellent, communication with Sonja was great, very clear. Trudy showed us in when we got there and was very helpful and was easy to contact throughout the stay.
