Marta's apartment is a perfect base for exploring Lisbon and the surrounding area. The transport links are exceptional and Marta is a great source of information on what to see and how to get there. We were a party of 12 friends in our 50s and 60s celebrating our friendship and a couple of big birthdays, we could walk easily into the old town or catch the nearby tube.
The apartment is spacious and clean with a little balcony outside to sit on if you fancy some sun. The water was always hot even with so many of us and we never felt cramped. We didn't actually cook in the flat but the kitchen was clean and well equipped.
I would happily recommend this place to anyone.
