We had a great stay at the apartment, which could not be in a better location in Lisbon. Right by Alfama and an easy walk down the hill to the city center. There's even a public elevator down the hill if you don't want to deal with the climb back up!
There's a great little grocery just up the street for any supplies you might need and lots of little restaurants and cafes within a block or 2.
Communication was great on arrival and the apartment is beautiful, with stunning views, original tile work and old wooden floors. It's quite sparsely decorated though and in the IKEA mode, so the furnishings unfortunately don't reflect or complement the character of the apartment. Our only major gripe was how uncomfortable the beds were. They are all single beds and felt like sleeping on a board. And pillows are the the thinnest little pillows and only one per bed. My husband actually slept on the couch in the living room after the first night because he had such a bad night's sleep in the bed.
It's a walk-up on the top floor with no elevator. It didn't bother us but be prepared to lug suitcases up several flights of stairs.
Overall we had a great stay and despite the bed situation would recommend a stay here in the heart of Lisbon.
