The flat is just on the edge of the Alfama neighbourhood, which is lovely area to explore, with lots of narrow winding streets and hidden cafes and restaurants. Expect to see neighbours leaning out their windows having conversations. It was about a 20+ minute walk to more central Lisbon, and can be a little uphill on the way back, but overall a really enjoyable walk with loads of nice views.
The flat is almost like a basement flat with access to terrace, but that meant that the flat was nice and cool (and even cooler once you turn on the a/c) I also liked how quiet the flat was, hardly any street noise, which made it easy to fall asleep. The kitchen doesn’t have a oven, but there’s a cooktop and a microwave and plenty of pots and pans. The terrace is also lovely with a view of the water and felt very private.
