Great place to stay in a great area of Lisbon. Getting around couldn't have been easier being based in Alfama. Loads of restaurants, cafes and things to do around the apartment and you're not far from the water at all.
Only minor thing I would say is that the pictures make this place look much bigger than it is, but that's completely fine- 3 of us still managed to stay here pretty comfortably.
Would definitely recommend staying here if you're heading to Lisbon.
