Both Mariana aswell as Carlos, who welcomed us on our first day, were very friendly. We enjoyed our time at Mariana's a lot and we felt at home during our stay there. The apartment has everything you need, a kitchen with oven, stove and fridge, a washing machine, and a bathroom. The room is basic, with table, wardrobe and double bed, but bright as it has two windows. It is located centrally and most can be reached by foot. A park with beautiful view is close by. The only disadvantage is that it is located on a small hill, which you have to walk up to reach the apartment. That's ok for everyone in good health. One of Lisbon's old, famous trams drives outside the apartment, which can be noisy during morning and daytime, but definitely adds to the typical Lisbon atmosphere. Overall, we had a great time and would strongly recommend the room!
