Emma's apartament is a perfect place if you plan to do sightseeing in Lisbon on foot. All important destinations such as viewpoints (miradouros), Rossio Square, Praça do Comèrcio, the streets of Alfama are within a walking distance. The flat is placed in the last floor and in a sunny summer that's an advantage because you can feel a cold breeze blowing from the Tagus. What's more, the view is really stunning. The apartment is well-equipped, a washing machine and a dishwasher were very useful. The only drawback I can think of are steep stairs outside and slants on the apartment, I'm not a giant but I had to be cautious. I would definitely come back.
