Antonio's place is a good place to stay. It is about 20 minutes from the City centre by walking. If you don't want to walk, there are many transit options to get to the centre. The place itself is very clean and Antonio is a really nice host We only saw him twice while we were there, but every time he was very nice. The room is a good size for 2 people and even had a sink in it which was super convenient. There were a couple of things that were not that great. The bed was very squeaky and a bit uncomfortable and the WIFI was spotty (connecting and disconnecting at random). We also had the room closest to the main door so we could hear everyone coming and going as well as the bell from downstairs. If you could get over these minor issues (which honestly, we did) then this is a good place to stay while in Lisbon. It is good value for what you get.
