Great hotel in the very center of Lisboa: it's the best place if you want to hang out in the Alfama and Bairro Alto neighborhoods (it's exactly in the middle, so you don't have to climb up every time both hills), it's 5 mins far from metro station taking you directly to and from the airport, and 5 mins from the railway station that could get you to Sintra.
Our room was a smaller than those in photos and without balcony but very clean and super comfy.
To sum up: highly recommended!
