Helena's flat in Lisbon is lovely. Centrally located a stones throw from pretty much everything (if you're game you can even walk to the castle, which is just above you). The flat has a lovely little terrace with an amazing view over Lisbon..
Helena is a great host, from organising taxis and helping us orientate ourselves, she was great.
We had a lovely stay and the flat is more than comfortable for 4 adults or a family.
