Great and easy stay at Luisa's place, the apartment is well organized and well located in Alfama, a nice typical area. There is a very tasteful bakery just 50m down the street we would highly recommend for breakfast! Luisa was nice and helpful, despite our late time of arrival in Lisbon.
Only 2 things to have in mind before coming: the place is noisy, you can hear the neighbours from upstairs/downstairs quite loudly, especially when sleeping on the couch in the living room. And the stairs to reach the apartment are very steep, you'd better have small suitcases.
Thank you again Luisa!
