We really enjoyed staying here! The apartment was beautiful, a fourth floor flat near the Basilica that was impeccably clean and had everything we needed. We were welcomed by Paulo, who gave us a helpful orientation to the apartment. There was plenty of space for three people and a lovely view of the Tagus River.
Worth noting (though it did not impact us), the bathroom is quite small, especially the shower, and the bed's mattress very firm. We usually walked uphill back to the flat, which was a fairly long, steep climb, but taxis provide an affordable alternative if you don't want to walk. Overall, we definitely recommend staying here.
