The apartment is elegantly decorated and stylish as expected from the nice photos. Fantastic location to explore Lisbon, Bairro Alto is a charming area with many interesting sights and vibrant night life (can be slightly noisy outside in the evening but quality windows keep the noise out). If you are carrying large suitcases be aware that the building has no elevator, but 2nd floor is manageable.
In our case it was a self check-in but owner was very responsive in communications and ensured any question/issue was resolved promptly, even going the extra mile when needed. Look forward to staying again in the future!
