Mariana is an AMAZING host! Couldn't have asked for a better family to take me in during my very first months in Lisbon. Not only is she kind and extremely helpful, Mariana is very welcoming and makes you feel comfortable and cared for. I have many wonderful and happy memories of my time in her home. Plus David and Zeus (the kitty) made my life much brighter and filled with laughter. It was a joy to live there with them. The home is well equipped and the view from the kitchen window is to die for. The wooden staircase that leads to the flat is a great workout as well :)
The apartment is located in the historical part of Lisbon and close to everything you might need: two subway stations at a comfortable distance, 3 supermarkets (Auchan, Lidl and Mini Preço), the elétrico is also right there in the corner if you want to take it, and access to historical sights and neighbourhoods such as Mouraria, Alfama, Graça, Baixa and Chiado is easy. I'd often walk to those places. There's also a nice supply of smaller, family owned stores (bodega style) and asian markets.
