I began staying at Airbnb locations in 2014 when I lived in Cairo, Egypt. No matter what city I was visiting - Copenhagen, Prague, Vienna, Budapest, Venice, Paris - the Airbnb locations were always an important and sometimes crucial element that could make or break the stay. I’ve never stayed in a more perfect setting than in Emma and Rui’s tower home in the exquisitely beautiful city of Lisboa, Portugal. Amply supplied with everything and more than a traveler would need, the gorgeous space had three floors that contained two double bedrooms, two baths, a living-dining-kitchen area and a rooftop deck with an almost 360 degree view of the Alfama district and the Tagus River. Even more, Emma stayed in close touch with us in helping to identify places where we could go to get the testing we needed in the age of COVID in order to travel. True, the home is not for the faint of heart when it comes to climbing stairs, for there are many to negotiate - in the building, in the home and in the neighborhood. But this 66-year old retired teacher and his 56-year old traveling companion would never want to stay anywhere else!
