Rui's flat is in an amazing location within easy walking distance to Cais do Sodré (with trains to Belém and Cascais) and central Lisbon. The flat is comfortable and clean, with amazing views overlooking the city and sea. The only downside is that there are a lot of steep stairs to reach the flat and the building itself is on a hill, so I wouldn't recommend it for people with accessibility issues. Otherwise, I'd strongly recommend it.
