The apartment is in perfect condition and exactly like the photos - clean, light, airy and very comfortable. All the appliances are really modern and there is enough cooking equipment to make meals in the flat. I stayed for 3 weeks and Alexandra was the perfect host, with quick communication and going out of her way to replace an old pillow for me for a more comfortable new one.
The street the apartment on is in a very good location - a short walk up the hill to the centre of the Graça neighbourhood (about 10 minutes), where you can find tram and bus links, and lots of shops, cafes and restaurants as well as incredible viewpoints. If you walk a few minutes down the hill from the apartment you will arrive in Campo de Santa Clara where there are a number of cafes and restaurants as well as the Feira de Ladra market and Pantheon. The big Santa Apolonia train station where you can get the metro and trains, is a close walk down the hill too. It's a really safe and clean neighbourhood in the day and at night.
The only small thing to bear in mind if you're a light sleeper is that with the windows open, you can hear traffic on the road which is sometimes noisy late at night or early in the morning. But with the windows closed the apartment is peaceful. I would definitely recommend staying there - it's comfortable, beautifully light and very well located for enjoying Graça and Alfama, as well as the rest of the city. And Alexandra is a great host - thank you!
