We had a fantastic time at Ana and Mariana's place. Lisbon is such an amazing city and the apartment is very well located for the old town - Alfama and the castle are walking distance, as is the main shopping district. They were great to deal with and provided loads of information. The apartment is compact, but very well-stocked and thoughtfully decorated. There is no aircon, but they provide a huge fan for the bedroom... Highly recommend this place.
