The location is fantastic - we felt centrally well located to the nearby monument which had a square where there were always taxis. We could easily walk Liberdade Ave. The restaurants near the AirBnB were fantastically located, too.
I would not plan on staying here, though, if you intend to cook meals in. The kitchen offers less overhead clearance than most American crawl spaces and gets progressively narrower as you progress towards the sink. Additionally, there wasn't a great volume of clothes storage (4 small vanity drawers) if you don't intend to use the wardrobe to hang everything (which, the number of hangers available was slim). Finally, check-in was difficult. The host was not in town as she is a student elsewhere, and her mother/the cleaning staff largely did not speak English. Even after trying to display the airbnb app and share the name of the listing/host, it seemed difficult to confirm and get into the unit by happenstance. Had I known more Portuguese this might have been avoided.
The location and balcony were fantastic, though, and on more than one occasion did I find myself getting lost in the view off the balcony of the city. Flavia was responsive and overall we had a good time. I'd recommend this listing to budget-minded travelers who hope to see much of the city by foot.
