My mum and I had a really good experience at Anna's apartment. It was mt first time visiting Lisbon but my mum's third. The location was fab- good metro link (3 min walk) although on a hill so if you have bad legs or are elderly this might not be the best for you. However this also means you get a great view! Its a few minutes walk from a couple of lovely miradours too for more amazing views.
The apartment itself was well equipped with good wifi, a lovely balcony, washing machine and cooking facilities. The bed was very creaky but otherwise everything else was great! The building has so much character.
The only trouble was at night if you come back to the apartment and it's dark, there dont seem to be any lights in the stairwell which is a little dangerous for someone elderly or unsteady on their feet, or if you dont have a torch. We had to feel our way up the stairs.
