Dianka's flat is the perfect accomodation to enjoy Lisbon, many points of interest are within walking distance (we walked a lot) and the metro station of Baixia is just down the street.
At night, you'll find yourself in the middle of Barrio Alto craziness, with many bar and people enjoying the night life but don't worry, being at the 5th floor, your sleep will not be compromised by the noise of the crowd.
The flat itself is comfortable and very well equipped.
