I spent a very good holiday in Mary Anne appartment. Mary Anne, and his husband, are very kind and available for any helps and questions.
The appartment is very good located (center of Valetta) neer restaurants, bus stops and main places to see in Valetta.
I recommand this appartment if you want to stay in Malta (visiting temples, cathedrales, caves, islands, cliffs, colorful balconies..) for few days or more.
