This apartment is great! perfectly located in the centre of Lisbon making it very easy to get around! The apartment is wonderful - 2 large rooms making it very easy for 2 travellers to stay and have their own space rather than being cramped into a small space.
Note that the street is a pedestrian street so if you have a lot of luggage, you won't be able to get a car right to the door, but just 1 street over worked perfectly for us.
The only other thing to note is that the stairs are quite steep and long - if you're not as mobile they could be problematic.
Overall I can't fault this apartment - Everything suited me perfectly!!
