I stayed at Martin's townhouse for about a month. it was well-appointed, comfortable, and in a lovely location a stone's throw from one of many great sea views from Valletta. It takes about 10 minutes to walk to the commercial/tourist centre of town from this residential area. For those who are not fans of hills there is a convenient bus stop to the terminal. (The route offers more great views of the harbour.) From the centre it is another few minutes' walk to the bus terminal which will carry you to most parts of Malta and to the Gozo ferry.
Less than a minute up the street from the townhouse is a grocery, a bakery, and a pastizzi place.
Martin's place has everything one could need for a comfortable stay: the kitchen has enough equipment to make a banquet, should one desire, and there are two huge bathrooms and a commodious wardrobe/dressing room.
Martin was very welcoming and communication was good both in advance and once I'd arrived. He also has a stack of local travel information to peruse.
I enjoyed my time on Malta and the accommodation was a big part of that.
Wouldn't hesitate to stay again.
Thanks Martin!
