João's apartment was perfect for mine and my friends stay in Lisbon. It's on the edge of a gorgeous Miradouro so even when you don't want to go far to do something for the evening you can go up and listen to live buskers and buy things from little food trucks. The apartment has a lovely big bathroom, and a well equipped kitchen which we needed for a 2 week stay. Graça is a beautiful and so close to the centre but far enough back that you can chill out if you would like to. I couldn't recommend this apartment more.
