Doris' wonderful apartment was perfect for us - two couples. It's in a great location, very roomy and comfortable, and with excellent amenities (including an ingenious clothes-drying rack and good wi-fi). We appreciated the wonderful jam and goodies that Doris had left for us and her hospitality. She also arranged a reasonably-priced and on-time transfer to the airport for us when we left. We wish to come back to Lisbon and stay at Casa Gloria again, and would highly recommend it to others.
Tips: Our favorite restaurant was the Quermesse just around the corner + the Alfama small-group walking tour with Context Travel.
