Pedro's place is located in quiet part of Alfama - not all areas of Alfama are quiet. The apartment is wonderful: easy, comfortable, clean, good internet, etc.. We met Pedro' s mom - who gave us a nice overview of the place - but didn't get the chance to meet Pedro. We were out a lot :).
The house is close to the Castle at the top of the hill, which makes for an easy walk down through the winding, crazy streets of Alfama to find food, music, shops and so on. There are several nice restaurants right there as you walk out the front door, a good market for supplies, and an amazing coffee shop and bakery (Copenhagen Coffee Lab) all within steps of the front door.
The trolley that should run right by the front door is suspended until some rails and roads are repaired, but you can make the walk up from the Rio Tejo or the Praca Comercio/Chiado areas if you take it slow (we're in our 60's and did it every day) get public transport up to the castle and walk down, or just take a cab or uber to the front door.
In sum, this apartment is wonderful. Pedro and his mom take beautiful care of it and it's in a fabulous location.
