Great room, great host!
The house is spotless and cozy, included the kitchen and the bathroom (awesome shower!). It has an outdoors sitting area we did not use, but which looked like a great place to have breakfast or dine at.
The room is spacious, private and quiet. It has a dressing room where one can leave any luggage, with even a closet for the visitors to unpack if they want to. And the bed is great! Also, internet is working perfectly, so you can check for new places to visit at the end of your day.
Close to the place you can find convenience stores, in case you want to buy stuff to cook at home, but also bakeries and some tascas (small, cheap restaurants) in case you want to eat out.
Regarding transport, you have two different Metro stations (Intendente and Anjos) literally 10 mins walking from the house, and less tan 5 minutes from the door there is a stop for tram 28, which will take you to the Castle and the city centre. But I really recommend you walk around, as the castle is some 20-25 mins away, and on your way there you can pass Bairro Estrela d´Ouro and the viewpoint at the Senhora do Monte church. Also, the neighborhood is quite nice, with some déco and modernist buildings.
Finally, Cristina is warm and welcoming but still left us all the privacy we wanted, and she is always ready to offer tips and advice about the city. She asked about our day, offered some good advice regarding what to see and where to go, and checked regularly to see if we were ok with the room or if we needed anything else. She made our stay nice and easy :)
All in all, a great place to stay when visiting Lisboa... if we go back there, we will try to book it again!
