We were only in Lisbon for a couple of nights on our way home back to the states from several weeks traveling in Europe. It was the perfect space for a short, end of the trip stay. It was located in the perfect area for us, as we're in our mid-twenties and wanted to go out at night in youthful areas in the city - which Santa Catarina was perfect for. It felt very central to everything, so we could easily get to Barrio Alto for amazing food, drinks, dancing, etc. It was also an easy walk to the water and really everything we could have wanted. The terrace of the house is INCREDIBLE, with an absolutely stunning view of a part of the city - which we absolutely loved. The shower door didn't close all the way no matter how I tried to get it to shut, so it wound up leaking water every time we used it which was just a bit inconvenient to clean up but I'm sure can be easily fixed. The apartment itself was gorgeous and spacious, given it's a fourth floor flat. Communication and check-in was very easeful and they made sure we were well prepared to check-in and things were super breezy in that regard. I would definitely recommend a stay at their space if you're coming through Lisbon!
