Great location and great hosts - responsive, attentive and helpful, cannot fault either of these. Antonio and his wife are such lovely people and I used a few of their recommendations for eating in the area. They were very quick to respond, too, solving minor issues immediately. Comfortable and lovely apartment with a few caveats: as many old buildings, it has very low ceilings, especially in the shower (guessing 1.9m max height). The sound insulation is not great, either - I heard more of the people staying upstairs than I would have wanted to, but if you are not a light sleeper, maybe it is not a big issue. Otherwise, a great base to explore and enjoy Lisbon!
