I'm happy to recommend Melis's apartment most warmly - it is spacious, quiet, comfortable, attractively furnished and in a fantastic location. The kitchen is well equipped if you want to cater for yourself. Principe Real is a really delightful neighbourhood to explore, and you're only a short walk away from Bairro Alto, Chiado and Rossio. All arrangements went smoothly. Mr Carlos met us at the apartment and showed us around - he was very helpful and friendly. Top tip: climb the steps nearby up to the Miradouro de Sao Pedro de Alcantara and reward yourself with stunning views over Lisbon (and a drink or two from the lovely bar there!)
