Highly Recommended! We spent about a week in the apartment and felt very comfortable. The location is great. Old town, metro station and supermarket are right outside the door or around the corner. The apartment itself has everything you need for a comfortable stay and much more than we expected from an airbnb apartment. The dishwasher, washing machine, food items such as coffee and pasta as well as a small welcome pack or bath items made our stay very comfortable. The terrace is pleasant and even with our one year old son everything was easy. The high chair was convenient and the existing sand toy was also allowed to go to Cascais. ;)
I can only recommend this apartment and the great hosts. I've seen a lot of good Airbnb apartments, but this visit puts it on top.
