Had a great stay here. Very central to the quant Fado area and only a short walk down hill to the train station and bus stops. Coffee shops close by to grab one on the way out.
Yeah there are steps up to the apartment so don't have very large suitcases, but other than that being young and fit is no problem.
Easy to get a cheap Uber up to the apartment 'area' if arriving by public transport and then just walk a few min down to the apartment, save hauling it up hill.
Great location to stay if you'll like to visit a quiet area of Lisbon, but easy to get to other sections like Bairro Alto within relatively flat 25 min walk.
