Value for Money!
Very nice, welcoming host, great view of Alfama, everything you need in the apartment is there. About 800 meters to the main square (with a small uphill/downhill), 500 meters to the metro, 150 to the bus and tram.
Due to the hillside and narrow staircase the apartment is not for older than 65 or 70 but Lisbon is a city on 7 hills.
In any case my recommendation:
1) due to a correct apartment
2) a friendly host and
3) a nice position
