We loved our stay at the flat, immersed into the Alfama neighborhood. Sights, good restaurants with local cuisine and authentic Sangria are in walking distance. Apartment was clean, spacious and you can see the river from the balcony . It can get noisy and hot, but that is the vibe of the area. Fans are in each room to offset warm temperatures and the airflow is easily mananged with opening windows and balcony doors at night.
Artur is a wealth of knowledge as far as recommendations for things to do.
