I think it's the best place where we've ever stayed. Nice hosts, large bed, fully equipped kitchen, many cool things around like restaurants, subway station, flea market and many more! We really can't find any minuses.
There was only one (but still, positive) moment I should mention about. Near the apartment, there were construction works, which Susanna warned me about in advance. And then, it was very nice when we met her brother Andre and he suggested us ear plugs so that we felt as comfortable as possible.
Thanks for a great stay in Lisbon!
