Simon's place was perfect for our one week stay. I went with my family and we enjoyed the 2 bedrooms with doublebeds as well as the smaller one-person bedroom. The living room and the kitchen were big and well equipped. The garden is nice although the weather was not friendly enough to let us enjoy it properly.
The area is very calm and quiet, it is surrended with nice brickhouses near a park. I definitely recommand Simon's house for a stay in Manchester, if you have a car you will be in 15 mn in the city centre.
