Good place to stay in for few days in Lisabon. As long as you are out the whole day exploring the city it is ok but if you would like to spend more time in the studio, the lack of day light might be little but disturbing for some. In the appartment you can also feel the smell of moiusture and the only way to ventilate the place is through the door window. To be honest that was not a big problem for me but you should know it before booking :)
