This. Is. The. Place. It looks exactly like on the photos, is very spacious, everything works well, everything is thought-through, there is a great range of cooking utensils (shout out to the garlic press) and we very much appreciated the high quality interior design (shout out to NOT having pictures of trams and Lisbon sights and to the lovely rotary light switches) and soothing colours. And the view: There is nothing better than to sit by the living room window (maybe with a glass of red wine) and ponder life looking at illuminated Sé Catedral at night. The balcony view is over a sea of red-tiled roofs and also very soothing. Everything feels very private.
Diogo was very nice and responded quickly to any needs (and there were not many).
One slight disclaimer: The churchbell on the balcony was functioning when we were there - 3 or 4 times a day, Sundays more often and more extraverted :) It is not too loud and rather charming really, just be prepared.
