Ana's apartement is just beautiful! It offers a breathtaking view over the river and the beautiful terrace is also a great place to relax. We did as Ana told us: We walked down the hill to get to the city and took the taxi to get back up the hill to the apartement - taxis are really cheap in Lisbon.
Ana's place is a perfect starting point for exploring Belem or for catching the train to get to the beach, e.g. to Cascais. You should definitely eat at "Club de Journalistas", a restaurant just down the street with a beautiful little garden and delicious food.
Communication with Ana was easy and qucik, she was very helpful since we could check-in early. We loved to stay at her beautiful place!
