I stayed in this nice apartment for 3 nights arriving later on a Friday evening. Jorge was so kind to wait. Very clean apartment, bed and shower. Communication with both Diana and Jorge was very quick.
Location is in the old part of the town. A great start is to walk up to the castle in the morning. Its well located with the Appolonia metro just 5 minutes walk away. It is a steep climb up to the apartment though. If you know Lisbon a bit you will find this apartment very easy to reach day and night even by foot.
