Lovely flat which was very close to Rossio station and area. Nice and spacious inside, thankfully had stand fans in each bedroom as we were visiting at a very hot period in September! Location is great for Rossio station as train goes directly to Sintra. Lots of restaurants nearby (Solar around the corner has great seafood at the recommendation of the landlord's friend!)
The walk up to the apartment can be quite steep, so I'll echo the warnings from some other reviewers that you might want to consider an alternative if you are less abled physically.
Thanks Joana and Fred for a great stay!
