Lia was a perfect host, she's kind and funny.
The place is in a neighborhood 50 minutes walking from Lisbon centre; but there's a metro station 7 minutes away so it wasn´t a problem for us.
If you choose this house, be aware that you´ll share a home with more guests. For me, I think the house is full of life; but I think is not suitable for everyone.
Last thing, airplanes fly near the house so if noise is a problem for you, i wouldn't recommended; you get use to it quickly but it is kind of an issue.
For us, was a great experience and we won't hesitate on repeating.
