This apartment is amazing, the view is even more beautiful than at the photos.
The location is perfect - it's in the heart of Alfama - an old and charming district of Lisboa. The transport connection is also good - 7 minutes to Terreiro do Paco metro station, 10-15 minutes walk to Cais do Sodre(metro+boats to the other side of Tejo+railway link to Cascais) or Santa Apolonia (metro+trains).
The communication with Kiki was good and her valuable input made our stay even more pleasurable.
Please keep in mind that heavy luggage is not really a good idea - it's 4th floor(the 5th if you count the ground floor) and no elevator. And turning on the microwave and electric kettle at the same time may cause the light go off(it's easily fixable with the button on the counter near the front door).
And in case your map and/or Uber can't find the 4 4 building, search for 4 instead and, when you're there, look for the other 4 just around the corner of the same building, near the arc and souvenir shop.
