Nuno's place was true to pictures and exactly as advertised. It was extremely clean. The apartment is not in downtown but was less then a 10 minute walk to the metro which is 3-4 stops away from the city center. Getting from the airport was also a straight shot on the metro.
The light in one of the bedrooms was out but we just moved a lamp from the other room. We were a little nervous about the area but came in and out at various hours and never encountered any problems.
We never met Nuno but his aunt Gina let us in and his sister Sonia was very responsive via phone.
