Maria's apartment was lovely, and looks even better than in the pictures. It was much bigger than we expected and everything was clean and tidy. We didn't see Maria, but all the arrangements went smoothly and she replied to all our messages promptly and answered any questions we had swiftly. I would say that if you are less mobile then the stairs would be a struggle on the 5th floor, but it is well worth the climb for the fantastic views from the apartment! Great location too, with the main areas within 10 minutes walk. Stay here if your going to Lisbon!
