The location is perfect for exploring the nearby neighborhoods. We were able to walk easily throughout the Alfama, Graca, Baixa, Barrio Alto, and Chiado from the apartment. Markets, restaurants, views, river walk, etc are also very close as is the famous Tram28.
The apartment itself is huge. There is a large living room with views out to the river, a large bedroom with the same view, and a large kitchen/ dining also with the same view. The bathroom, too, is large with a bath/ shower, toilet and bidet. Everything we needed was supplied and Joana (an associate of Juan's), who is right outside the entrance to the building will get you everything including taxis (for early morning flight out of Lisbon), extra supplies, to advice.
The TV had many english speaking channels, the wifi was good, the apartment was clean and tidy, and there is plenty of light and air (large windows opening to river).
Our driver dropped us off at Rue Sao Joao da Praca but the apartment is actually on the Travessa Sao Joao da Praca - not a big deal because they are really close (and connected) and the locals were very helpful in pointing us in the right direction.
We loved our stay here and would stay in the same place again.
