Very nice apartment, it matches with the photos showed here on Airbnb.
We arrived in Lisbona on the 3rd August; Sara, Tiago's mother, welcomed us on our arrival - our flight was late but she was really friendly and helpful, she waited us for over an hour! She gave us some useful tips for our visit in Lisbona (restaurants, sightseeings, transports..). The house is beautiful and clean and it is in a good position (near to the train station and underground, in an area full of pubs and typical restaurants). The kitchen is very well equipped with everything you could possibly need (there is also a dishwasher and a washing machine), the two bathrooms are spacious and have nice showers.
If I had to complain about something, I could only mention some noises that come from the streets at night or early in the mornings if you keep the windows of the living room and of the suite room (the one with the bathroom inside) open. In conclusion, we liked the apartment, it satisfied our expectations and the hosts were helpful and nice.
I suggest you to stay in Tiago and Susana's house if you come to Lisbona!:)
