We enjoyed our stay at Marco's apartment. It's on the top floor of 3 with stairs only (around 3 flights but easily climbed). We liked that there was no one above us and it was mainly quiet at night, especially in the bedroom which is at the back of the building. There are 5 apartments in total in the building, most if not all are managed by Marco.
The apartment was bright, compact, clean and comfortable.
Bed was a standard double and was comfy too.
There are a few bakeries and cafes in the street outside and a pingo doce supermarket about 5-8 mins up the street.
We were able to walk to the Ribeira/riverside area in around 15mins. All downhill on the way there! We also enjoyed visiting some local bars and restaurants close to the apartment. Try aduela bar for drinks, Travessa restaurant for local dishes with a twist and Zenith cafe for brunch.
We walked to the Trindade metro station to get to the airport on our last day. This was about 8-10 min walk and cost €2.30 each.
