This apartment is, as we say in the Netherlands, klein maar fijn: Small but pleasant. If you don't need much space, this is definitely the perfect apartment. The atmosphere is lovely and the view from the windows is great. The apartment has a very comfy bed and the kitchen is perfect to cook dinner some evenings. The only disadvantage is that the walls and ceiling are thing and the upstairs neighbour can be somewhat noisy in the mornings. But we had our alarm set pretty early anyways, so that was not a problem. All in all this is a very pleasant apartment for your stay in Lissabon.
