Maria's apartment made my visit to Lisbon. I requested to stay at her place on the run and thanks to her responsiveness, I had a place to stay (fyi: there's wifi at the Lisbon Airport before customs).
Once I arrived at the apartment via Aerobus (€3.5 and about 20-25 minutes), I seldom had to take public transportation. I prefer walking and the apartment is really in the middle of everything. You can walk to barrio alto and alfama. What more can one ask for?
The place is small, but that's what I prefer. When I travel, I'm seldom in the unit anyway. The most important thing is the kindness of the host. I was welcomed with recommendations of places to visit, a metro pass, a mobile phone, fresh fruits, port wine, teas and coffee. The place was also really clean and stocked with all the essentials: French press, kitchenware, small tv, a washer and a fridge. Drinking coffee and looking out from this balcony is nostalgic.
Due to the proximity of the apartment and the warm greeting, I would stay here again.
