We truly enjoyed our stay at Nuno's place. He gave us a warm welcome and showed us around in the appartment. He even carried our bags on the stairs to the elevator :) The appartment was very clean and had all the comfort you'd wish for. there's even a washing machine and ironer if you want to wash clothes. the location is perfect, right next to the river, with alot of great restaurants nearby but still quiet at night. All main touristic points are within walking distance. And the good thing is: you only have to walk downwards to go home :)
small advice for future visitors: if you take a cab, don't give the exact adress. As the area was recently renovated and became pedestrian area (only accessible for authorized cars) the gps will go crazy. It's better to let them drop you off at the av. infante dom henrique or r. cais do santarem. From there on it's only 1 minute walking.
to conclude: we truly enjoyed our time in lisboa and Nuno has been the perfect host!
