The apartment and communication from Antonio were great. I don't have anything negative to say.
Pros: Location-walking distances to everywhere including Belem Tower. Space was very clean with cold air conditioning. Scenic view-every morning sunrise with the view of Sao Jorge castle.
Cons: 4th floor walk up. I mean, it is Lisbon every where is hills, it's a good exercise. For those who has legs or knees injury, wouldn't recommend. Otherwise it's worth the view.
Like I said, I enjoyed the space (it's very bright from natural sunlight) and its location. It has everything I need and close to all major site. 2 mins walked from apartment to the famous Ginjiha spot and a few more steps to Rossio train station to Sintra. Totally recommend.
