The apartment is lovely - cosy, spacious and well equipped and lovely part of Lisbon. You're 2 mins walk from Estrela park, once of the nicest places in Lisbon. Being able to walk in the park every morning - especially in the autumn as the trees went from green to orange and brown - was incredible.
There are plenty of shops, cafes and bars close by and you can easily reach the Chiado neighbourhood (full of restaurants & shops) and the historical centre of the city using the local yellow tram, which passes just by the door.
