The apartment is in an amazing location, great restaurants within 100m (Esperanca, Tapas with friends, Cruzes Credo) and easy walking distance to Alfama, Terreiro de Paco, the cathedral and most tourist attractions. We mostly walked everywhere or got the tram. Basilio is a great cafe close by for Açaí or pancakes too. Helena was very easy to communicate with, helped by providing a port a cot & high chair for our son & when we had a minor issue come up during our stay was willing to come over to look at fixing it.
Downsides to the apartment to consider are (1) it is located on the ground floor and particularly the main bedroom is right by the entrance to the central staircase for the apartment building, which means you get lots of road noise as people walk past the window plus noise late at night as people come & go from the building. (2) The seals on the windows are poor particularly in the main bedroom so we had a lot of cigarette smoke smell coming into the bedroom mostly late at night. Likely it was flowing down from the restaurants & cafes close by. We are non-smokers and this was a real disappointment for us. The smell was strong enough that we had trouble sleeping at times.
Otherwise in terms of value for money & location the apartment is great & exactly as the photos show.
