The apartment is great. It was just myself and my girlfriend but would be fine for 6 people too. Kitchen is really well equipped, place is very clean, internet is good, right next to train station / Metro / supermarketand has a nice view too. Lisbon center is only 10-15 minutes walk or 2 Metro stations away. Omid and Diana are also great hosts. Very fast communication and will help with anything you need. Highly recommended!
