The flat is spacious and next to the viewing point with superb panorama of Lisbon. We really liked the location and proximity to Alfama. Luis is a superb host, responsive and accommodating. Definitely recommend. The only thing to note was that the flat is on the ground floor and given the age of the building - which I believe would be the same in any flat in this area- has ventilation challenges. You can't then just leave with the windows opened but once in, you can just open the windows and it's all fine with the fresh air.
Thanks again Luis for accommodating late checkout request and being there for late check in all the question!much appreciated
