I can highly recommend Joanna's apartment. The location and amenities are great and all that you need.
The apartment is bright, cosy and comfortable with wonderful views.
Alfama is a great neighbourhood in Lisbon, very vibrant and friendly. There is plenty to keep you occupied in the area and all other sights in walking distance.
Joana was very prompt to respond and helpful with any queries that we had. I would definitely stay here again.
