Lovely little apartment. We were there in April and caught the sun directly from about 12.30 - 4pm - the outdoor space is a sun trap! Very clean and modern, with everything you could need. Quiet residential area, but on a hill, so therefore close to a lot of viewpoints (miradouros) and then only ten minutes into the Alfama district where there are lots of restaurants, cafes etc. If you're on a budget, grab a few beers from the shop and head to a miradouro, people are hanging out and drinking there, but not in a rowdy way! Very chilled! There's a supermarket just around the corner, the 28 tram stops there too and the nearest metro is about 15 minute walk.
Teresa did not meet us, her neighbour did, who was very welcoming and had lots of advice and tips for us. Good experience overall!
