If you want to experience genuine Portuguese atmosphere added an aesthetic tuch, you must hire Marta's apartment.
The apartment is nice, clean and very spacious. The balcony gives you views of the river and the pleasant street. There are fine shopping around the corner and you can go down to a large station from which you can transport you around Lisbon by bus, train or metro.
Communication with Marta was very nice and she was very flexible when our flight was delayed.
I would recommend Marta's apartment to anyone who wants to experience Lisbon at its best
