Nice simple apartment in Alfama. Good access to public transport (train station/metro/busses). Supermarket in Apolonia station.
I traveled in March and did not experience excessive noise outside with the windows closed. It’s an old house with thin walls however with earplugs I could sleep well - but probably not suitable for people who are looking for quietness. I was a bit disappointed by the kitchen equipment (in comparison to its size), but most basic equipment was there to do some cooking.
