I had the best possible time in Lisboa by staying at Sergio's place. Here you will have a truly local experience: shops, pastelarias, restaurants, groceries, and the subway – everything at hand –, without the overpriced, annoying hassle of other more touristic areas (which are anyway 10 min away, when you do opt for it).
The apartment is spacious, truly well-equipped, and the outdoor seating area is a bless! The shower is strong and the kitchen equipment is cutting-edge. Also loved the dedicated work space, and the wifi is fast. The area is quiet, ensuring good sleep, and the 2-minute uphill stroll to get to the building will only make your legs stronger. Can't wait to come again!
