I stayed at Martha’s apartment in Lisbon with two of my girlfriends.
Marco checked us in and gave us a quick tour of how things work. He was very helpful in getting the toilet fixed except that the issue wasn't sorted until one day before we left which made things a bit uncomfortable for our stay.
That was the only issue we faced, other than that, both Martha and Marco were easily accessible and replied to messages promptly.
Not sure if this apartment is suitable for families with little kids as the staircase is pretty steep and is located on the topmost floor.
This apartment is spacious and airy and just like in the photos.
It is perfect for a group of friends to stay in the heart of Lisbon. What we absolutely loved was the location of the apartment! It was fantastic.
