This is one of the most stylish Air BnBs I have ever stayed in. The facilities and view (wow) were fantastic, and the location was perfect. It is located right outside the entrance to the Castle of Sao Jorge, and at the top of the (sometimes steep!) cobbled streets of Alfama. There is a bus-stop for the 737 just around the corner, which takes you right down into central Lisbon (Praça do Comércio) or you can take the short walk down the hill to get the famous No. 28 tram. I can also highly recommend the Wine Bar do Castelo just around the corner - some amazing wines and charcuterie on offer from the most knowledgeable staff!
Patricia is also a fantastic host, who is always on hand with a swift response if ever you had questions. I highly recommend any of her apartments!
