We stayed 2 weeks at Martin’s place and overall very much enjoyed it! The veranda is a must and the heater, as we were there in December, was much appreciated.
The apartment is well equipped, the bed was comfy and the Internet was fast enough to work.
As it is located close to the Tagus, being able to walk or run by the river was very enjoyable.
We had a car for the weekend and were always able to find a parking spot.
It’s a bit far if you want to reach the center of Lisbon by foot but bus/trams or fun electric scooters can help!
