The view from the balcony was simply amazing - definitely worth the going up to 6th floor. The apartment is well equipped and clean, however since we stayed in February, the bathroom was a bit cold - it's connected to the balcony and the door doesn't close properly, so it does get chilly.
Location is very central - on the map if definitely looks further than it actually is. However, the area is not the best in Lisbon - if I would've been alone I would've definitely felt not safe. Lots of drug dealers/users at night in the streets which makes the vibe feel a bit unnerving, however we did not have any problems in those 3 nights of our stay.
Overall we are very happy with our stay, thank you for hosting us!
