I stayed at Castle Inn in July 2015 and it was fantastic. The room was perfect for two people and the location couldn't be beat. Inside the castle wall and walking distance to everything in Alfama and the surrounding areas. If you have problems walking, the location may be difficult as it is uphill but otherwise, it was great! Abilio was very helpful, answering questions and providing help in a swift manner and the neighborhood shutdown early enough in the evening to have a decent nights sleep. I would definitely stay at Castle Inn again.
