Had a lovely stay at Andreia, Lays & João’s place in Rossio. Everything was exactly as pictured and explained on Air BnB.
The apartment is in the middle of Rossio - right near the Rossio Metro and suburban train station as well as a short walk to Alfama and Bairro Alto. I couldn't imagine a better location. João checked me in and out on time and was super friendly and helpful in answering my questions. They also left a welcome gift which was a really nice touch.
If you're planning to cook in the apartment - the kitchen has all the needed cookware / utensils and there is a grocery store close by. The apartment has plenty of natural light in the mornings and was a lovely place to make breakfast.
The walk up the hill + stairs to the apartment may be strenuous for older people or people with a disability. But, it is a short hill so no problem for people without mobility issues.
Overall, I have no complaints and really enjoyed my stay in this apartment. I highly recommend it for a visit to Lisbon!
