First, I'll start by saying what a great host Omar is! He was great communicating with us before we arrived and greeted us when we arrived. He walked us through the apartment to explain everything, then gave us a map and pointed out several local attractions and gave us the lay of the land.
The apartment itself was perfect for us, and it was very nice to have a king sized bed. It's in a somewhat busy area, but you wouldn't know it when inside because we heard very little street noise. The highlight is definitely the terrace - it was a great spot to sit and enjoy a drink before heading out for the evening.
The only potential negative depending on what you're looking for is the location. It's a more residential and/or commercial area, so there isn't a lot of nightlife, bars and restaurants to walk to. It isn't Alfama or Barrio Alto, for sure! It was fine for us, as we wanted some peace and quiet, and the livelier neighborhoods are just a short and cheap Bolt ride away.
I wouldn't hesitate to stay here again on a future trip!
