Even though the pictures are already impressive, it still does not compare to the real thing. Marta's flat is 20 meters away from one of the nicest "Miradouros" of Lisbon and waking up to that view is breathtaking. Apart form that you have nice pastry shops and markets around the corner and if you don't mind a little hike through the hills of Lisbon you can reach all major sights quickly.
The apartment itself is rather small, but basically all you need. The bathroom was very clean and Marta provided me with sheets and towels. Her friend Sara helped me settling in and gave me some tips where to go as a first-time-lisbon tourist.
Sadly I didn't meet Marta in person, but still it was a very nice experience and I can recommend her place any time!
