Luis' place is wonderful, if only for the view from the terrace. A bit noisy at night, since the area with bars is near. Since near the Barrio Alto, it's a lot of climbing and stairs, up and down, which is quite healthy, it obliges to exercise!
Luis was very friendly and helpful, and the place is fitting for 5 people for a short stay of 4-5 nights. The lack of a washing machine is the only minus, al the rest is very comfortable. A really nice restaurant next door, where we ate 3 times in a row, and a beautiful Miradouro at 3 min. climbing stairs.
We can recommend his place very much, and next time in Lisbon we'll go back there.
