This beautiful and very convenient flat is located in a busy district close to main touristic attractions. It's on the fourth floor of a building without elevator and with very narrow stairs so if you have heavy luggage it might be problematic to get it up. But once you get into the flat you forget all the inconveniences. The flat is very stylish, comfortable and well equiped with everything you might need during your stay. Wifi is stable only in the leaving room but there's a small remote wifi router that you can take to the beadroom or even outside the flat to have permanent access to the internet.
Me and 2 my friends strongly recommend this place and we'd gladly stay there again when we're in Lisbon.
