The AirBNB was perfect. It was situated in the lovely neighborhood of Alfama. Marco was a great host - he helped us out on anything, gave some good recommendations'&was very friendly. The AirBNB was just as described in the description. You'll find everything you need for a couple of days in Lisbon. Keep one thing in mind: you need to be a good walker to walk up'&down the narrow streets of Alfama and to climb the stairs @the AirBNB.
Don't hesitate, I highly recommend Marcos AirBNB.
