This apartment is fantastic. Clean, modern, has a balcony looking over rooftops to the Castle and the owners really have thought of everything a visitor could need. We got a warm welcome and it's location (close to the main town centre to access all the key points of interest, but with the beautiful local areas of Rato & Priniciple Real with slightly less of the frantic tourists) is ace. We never needed to use the Metro as all the main areas are easily accessible if you are happy to walk.
All the information supplied in the house folder was top notch with much detailed advice on what to see, where to go, where the owners like to go, and how to get there. The Aerial 360 at the local shopping complex is an absolute must.
We will certainly return to Lisbon in the future, and would be extremely happy to recommend this apartment to any future visitors.
