This is going to be a strange review, as despite the apartment being brilliant, I will not be coming back. The apartment itself is beautifully presented, perfectly clean, and in a dream location for access to the best parts of Lisbon. The balcony is more like a terrace, and has lots of space for sunbathing and eating out in the all day sun. Within a few seconds walk of the apartment there are incredible bars and restaurants, and shops for pretty much anything you need. Yes, the stairs up to the apartment are a little tight, but I am over 6ft tall, and had no issue.
The reason I will not be booking another trip, has also been mentioned in a couple of other reviews, and is the downstairs neighbour, an elderly local woman who seems to take issue with a great many things. Apparently, noise on the stairs and in the apartment are her main bugbears, and she manifests this frustration by waiting until you are leaving the apartment and then blocking the stairs as she launches a verbal assault at high volume. I do have some sympathy for someone who has clearly lived in the block for sometime, long before AirBnB was a thing, but the truth is we were super quiet, both on the stairs and in the apartment. After the first two incidents, we felt like we had to walk on egg-shells for the rest of the stay, and didn't feel comfortable leaving or coming back. My memory of the apartment will not be the brilliant stay in Lisbon, but the old lady shouting as us down the street from her balcony as we left. :(
