The apartment is on 3rd floor and stairs aren't the most comfortable one. But we've spent only one night there with two kids and it wasn't a big problem. The apartment is located close to the metro stations (Baixa-Chiado and Rossio), both about 3-5 minutes walking. There's everythin You need in the kitchen and bathroom. Heloiza was very helpful and flexible with our checking-in time and had some advices and suggestions what to do in Lisbon.
