You can expect a fantastic location, not too much noise, very hospitable hosts, with lots of great tips for the area. My tip is that if you need luggage storage to try Good Lock, Very short walk away, they have a resting area and bathroom and last-minute souvenirs to buy, as well. Also, across the street is a visually unappealing but delicious vegan restaurant & grocery, called Vegana? There, you can have a delicious vegan Francesinha! And vegan pastel de nata. Both are sincerely better tasting than they are non-vegan counterparts. To meat-eating men in our group agreed with this assessment.
The apartment has an iron and a combo washer/dryer, which was very convenient. And a nice balcony outdoors. There is even port and pastel de nata for the guest. We didn’t find it noisy at night, despite the fact that it was so centrally located. Slept well.
