Please note--there is a 20 Euro late check-in fee for check-ins after 6. It's in the house rules but we missed it because it was in French. Just a head's up for English language travelers. Before we got there, I felt that I would have booked something else because of this--but I was wrong. The apartment is so well located that I still feel we got a great deal.
Overall, this is a wonderful space. Small railroad style apartment on the second floor. Everything you could want. The location was amazing--in the heart of everything yet still pretty quiet. Short walk to restaurants, bars, major attractions, and not a far walk from every part of the city. Communication was easy.
Strongly recommend taking a cab to the apartment if you're arriving from the airport and have heavy bags--it's relatively close to a subway stop (0.9 km), but the walk is up a steep hill with cobblestone streets, so not ideal for roller bags. Taxis are very reasonable in Lisbon. The weather was good while we were there but it could definitely get hot in the apartment on the hottest days. That being said, it was close to 90 one day and we slept comfortably with the windows open and a fan provided by the host running.
