Agostinha is fantastic host!:) She is very helpful with everything. Her flat is also great, the room when we stayed was big, sunny, clean, with very comfortable bed.
In the kitchen you have all the devices and dishes needed to cook anything you want.
The flat is very well located. Close you have metro, 10-15 minutes of walk you have Graça, that is already an Old Town. In general you have all the old town within walking distance. Next to the flat there is a supermarket.
