It is a bit of a climb up to the apartment from Baixa, but then you get some great views from the apartment. The street the apartment is on is access controlled, so very little traffic and nice and quiet. The apartment was nice and big, the kitchen was well appointed and the place is very comfortable.
Close to restaurants, groceries, tourist sites, public transportation is an 8 minute walk away.
Helena was a great host and gave us some good tips.
