I have stayed in one of the studio rooms and met Isabelle and Joaos family, first of all I loved the warm welcome and kind hospitality they offered to me, the flat has couple studios with large shared kitchen and washing/dryer machine, everything is supplied by the owners, from kitchen equipment to detergents to shampoo/soaps, sanitizers, and i loved the nespresso machine with capsules offered.
The room was decent size, and the bathroom was large, there's a locker inside, and the room was clean and bed sheets were fresh, the bed was very comfy.
The location of the flat is 15-17 minutes walk to town, but its well connected by rato metro which is literally 3-4 minutes from the flat, the location is great, quite, and very safe.
I wouldn't look further when coming to lisbon, hope we meet again, thank you very much.
