This is a great apartment in a charming area close to a variety of food options, markets, a gorgeous miradouro (lookout point with kiosk) and the metro - though we never used it as the location is just a short, safe walk along the water (or through the winding burrows of streets) into the centre of Lisbon. We stayed for the NOS Alive festival and walked home from the train station each night/early morning no problems.
Excellent wifi and the apartment is spotless and surprisingly roomy. As per other reviews, the highlight was meeting Nuno who is just the best host! Excellent communication before we arrived, he checked in on us during our stay and would go out of his way to make guests comfortable - just as a small example, he hates cheese with a passion but still provides it in a basket of welcome snacks! Highly recommended. See you next time Nuno (we can get our own cheese next time too!)
