Highly highly recommend Sofia's place. While it is not downtown its so easy to get downtown with several metro stations close by. Even walking around the area is enjoyable, and it is closer to the ocenarium as well. Place was spotless, updated, great view of the street, and air conditioned as well. We didn't even need to use it though as place was cool in itself if you opened the patio door. It is on the top floor so be ready to walk up some stairs. Host was incredibly nice and thoughtful, was flexible with check in time, and went above and beyond by getting us a cab for an early morning flight we had as subways don't run at 4am. Even welcomed us with some Portuguese pastry treats and beers in the fridge. Wonderful place and host, probably one of the nicer places we have stayed our entire trip.
