The apartment has a perfect location, the Alfama district has been the best area for us in a lot of aspects. Super close to the Santa Apolonia station for the inter-city trains, bus stops, metro station, the flea market, and a lot of nice restaurants and bars around.
Marco's place is just as described in the listing, it is small but has everything you need for your stay. You could hear some noise because of the thin walls but nothing problematic.
Marco was a great host, communication was smooth, he provided quite some information and tips which helped during our travels. I would stay at this place again.
