This place was great and provided everything we needed and more! There is a beautiful backyard with a grill. Both the beach and the train station with access to the city center of Lisboa, Belem, and the beaches of Cascais are accessible within 5 minute walking distance. If you plan to experience the city nightlife of Lisbon, beware that the train to the apartment stops running at 1:00 am (more or less).
Christina was great as well. She was available for anything we needed. She even provided us with directions on how to use the metro and was flexible with check in and check out times. I would recommend this apartment to a friend!
