The apartment was small but lovely - exactly what you need for a couple. It was very clean and had everything we needed! The location (Alfama) is great, but can be an uphill battle (pun intended) if you have large suitcases like we did. It was really hot in Lisbon when we were there, so the apartment was a bit warm for sleeping but that was to be expected.
Overall our stay was great!!! And João and Carla (and Marco, who we interacted with) were helpful and very kind. Would recommend! :)
