We had a great time in Lisbon and staying at Mafaldas apartment was perfect for us. The neighborhood is not too busy but you are still close (walking distance) to most sight seeing spots. The apartment itself is beautiful. We loved the combination of modern and antique furniture and it is very bright. Since it is an old house you can hear the neighbors from upstairs and in the staircase. If you are a person that is very sensitive to noise you need to bring "oropax" :)
When we arrived Mafalda was there and explained a lot and gave us tipps where to go in Lisbon. She is very friendly and her information was very helpful. Thank you to her!
