The house is located perfectly between Baixa and Alfama, right in front of a tram no 28 stop that takes you on an amazing tour on streets of Lisbon. It's on the 3rd floor but there is elevator in the building!
It was clean, warm, exactly like in the pictures, well equipped kitchen for a longer stay, spacious bathrooms and comfortable beds. We got a detailed guide of Lisbon by hosts which was very helpful, with hand-picked places and some insightful advice about the city, its transportation and people.
Overall it was a great experience to come back there after whole day of sightseeing and conference, would recommend it for people wanting to feel the specific aesthetics of the city that like laid-back, chilled way of spending holidays.
