I literally cannot find words to fully express how wonderful our experience at Lisboa was; it has become probably my favourite city in Europe. And a lot had to do with Maria's loft: first of all location is as good as it gets, in Barrio Alto, close to tons of great restaurants (cevicheria, Tapas Bucho, Decadente and lost Inn, Clube de Journalistas, etc.) and stores (all walking distance). It is literally less than a block away from Mirador de Sao Pedro de Alcantara, one of the best spots to get an amazing view of the city; it is two blocks away from Sao Roque church, one of the most beautiful churches I've seen on Europe. Less than 10 minutes walking from Luis Camoes square and the Chiado shopping area; 12 minutes walking to Elevador Santa Justa, rua Augusta and the astonishing Rossio square. In summary, unparalleled location. Then you have the loft, some of the best (affordable) properties I've seen and stayed from the Airbnb network: really cool fully refurbished space, super clean and convenient; not to mention the terrace, which will provide you with an awesome view of Tajo river, April 25 bridge and Barrio Alto. Then you have Maria, a great super friendly and efficient host, making sure everything was perfect throughout our stay (from the complementary wine, beer and chocolate to all her tips on the city and her availability in case we needed anything); thanks Maria.
Trying to think on any downsides I would only mention that, given that this property is a loft, and like most buildings in Lisboa it does not have an elevator, you will have to go up four floors to reach the apartment. We were perfectly fine with it, but if you are traveling with small children (i.e. with strollers) or if you have any kind of disability, this could represent a challenge (although all Lisbon will, as it is a city full of hills).
In summary, great unique experience; we truly felt in love with the loft and with the entire city. We will definitely come back to Lisboa, and for sure stay at Marias loft again.
