Excellent location near to lots of fun bars and walking distance from everything - which made it ideal. It was extremely clean, a comfy bed and good shower and Carla even left us some pasteis de nata as a welcome gift.
There were some construction works going on opposite in the mornings which were quite noisy when trying to have a lie-in and the apartment gets very hot during the day however luckily most people will want to be out and about exploring Lisbon at that time anyway. For this reason it's not an apartment to spend the day relaxing in. Also the steep staircase was fine for us but could be tricky for anyone less nimble!
Overall had a great stay, it was everything we needed as a base for exploring Lisbon and Carla was so patient with our late arrival and trying to let us check-out as late as possible. Thank you and I recommend!
